Auto Resize Image Attachments (Avatars & Profile Pic Too)....

[mini2]

Gone

[TheComputerGuy]

cool. I like it a lot

working on www.runaked.com/forums

[Natch]

That's awesome - this is something I've been looking for for ages :D

Question: is it an easy thing to add this feature (maybe make your functionality into a standalone function?) into the Avatar upload and Profile pic upload functions ?

[Natch]

Thanks muchly! This was the one final hack I was waiting for from my ol' vB2 - I looked into it a couple times, but never had the patience ;)

[Symbian.info]

Does any one knows if it works in PHP in safe mode??

[MrNase]

I installed it and I hope it's working ;)

(It's working, thank you so much :))

[Erwin]

Very cool and useful hack. :) A lot of members are clueless when it comes to image resizing. This is a great idea.

[Symbian.info]

Has anyone with PHP in safe mode tried this out yet? I'm keen (as others might be) to know if it works?

Don't think it works :tired: I try it with the File Attachment Images Resize hack, when I upload a big files take a time and then many, many (50x) errors like this:
Warning: Division by zero in /home/website/www/forum/includes/functions_file.php on line 318
Warning: Division by zero in /home/website/www/forum/includes/functions_file.php on line 319
Warning: Division by zero in /home/website/www/forum/includes/functions_file.php on line 327
Warning: Division by zero in /home/website/www/forum/includes/functions_file.php on line 328
Warning: imagecreatetruecolor(): Invalid image dimensions in /home/website/www/forum/includes/functions_file.php on line 331

and then: IMG_0541.JPG:
File Too Large. Limits are 640 x 480. Your file is 1600 x 1200.

So far not working, I don't know if it the safe mode..

[lazytown]

There seems to be a problem with the avatar upload feature. If I set avatars to no more than 20K, but photos to 150K, it uses the 150K limit for avatars.

[lazytown]

For files that are too big (in K), I would still like to see it try and resize them -- then see if they come under the file size limit.

[CVMagic]

The issue with the deviding by zero in this hack is that you overlooked the fact that the hack does not define what $maxattachwidth & $maxattachhieght are... so besure to add those values to be edited in the admin panel....

^_^ by the way I coded the original version of this hack for vB2, look in the beta section for it, it should help you with some of the bugs in this one... FYI: Safemode shouldnt affect this scrpt as long as its not writing on to the filesystem. Also it helps to cache the resized images because trust me doing it on the fly will bog down the system in the long run.
Oh, I almost forgot if you have any questions feel free to send me a PM.

Be sure to restart your webserver and besure that php isn't complied with GD into it because then it will not run your newer version of GD... instead recompile PHP making sure that it points to your current version of GD... as far as the other errors they are just values that were overlooked when preparing the hack...

to mini: try to test for GD2 within the script with a function check on imagecreatetruecolor and if it fails then make it use imagecreate instead because it is compatible with all versions of GD so it will 1) make sure that the forum wont have errors in exchange for uglish images and 2) makes your hack compatible with earlier versions of PHP

[Blindchild02]

i get this error


Fatal error: Call to undefined function: unsharpmask() in /home2/xamira/public_html/forums/includes/functions_upload.php on line 292

[Blindchild02]

alrite, adding require_once('./includes/functions_image.php'); worked

[johnnyb]

I uploaded everything, and modified everything, but the images aren't resized?

[calvinnguyen]

Designed for: vBulletin 3.0.3 on a Linux server with PHP 4.3.8 and GD 2.0.23. PHP not in safe mode and attachments stored in the database. May work in other cases, but I can't guarantee that.

I had install it, but it didn't work for me.

[calvinnguyen]

If you have that configuration, it works.

1.Did you get errors, or anything?

2.Do you have your max attachment sizes set in the adminCP to start with?

3.Do you have a php.info file somewhere?
1.
I didn't get anything wrong, but I the size of the photo that attachment is not getting resize.

2. yes I had set the max attachment sizes

3. No, I don't have a php.info file

For set max attachment sizes, if we set it smaller than the photo size, after we attachment to the post , it will be resize to me equal the max attachemt sizes right?

[Natch]

Actually, there is a vB3 option to allow public viewing of phpinfo()...

[Blam Forumz]

Didnt work for avatars, everything else i dunno... :(

[outlaw621]

Using on vBulletin v3.0.3 with safe mode enabled in PHP and is working fine. The only other modification I had to do was to add require_once('./includes/functions_image.php'); to the start of the includes/functions_upload.php file.

[Blindchild02]

works great at - www.xamira.net since the avatar is on the homepage :) thanks alot!!

[lazytown]

I modded it slightly so that it resizes any image larger than the file limit or the dimensions limit.. However as stated, it probably does increase load on the server. The other problem is users are uploading photos like crazy now. :)

[remlle]

any idea when why when I upload an image that is 800k or abovr it fails. no errors just the upload page turns white with no writing on it.
also
in the file you recomended changing uploading to uploading and resizing attachments and I cant find that do you know where I could find that.

[Hexemer]

Hello,

first, thank you for this nice hack. :)

But, I have a Problem. :disappointed: The uploaded picture is "darker" than the original one.

attachment 1: original
attachment 2: uploaded in my forums

gd version: 2.0.12

Can you help me? :ermm:

[remlle]

same here.

[jarekn]

I still get the error That image is too large. The maximum dimensions are 220 by 220

vbulletin 3.0.3
Running on PHP Version 4.3.4

I only modified the functions_upload.php

No other errors are displayed...I can upload smaller images that are with in the 220 by 220 spec.

[Hexemer]

Where and how do I do the phrase change? I'm n00b at this. :)

Nice hack... thanks...

I have been looking for this hack..

EDIT:

Installed and working fine! I'm so glad I found this hack. ;)

Im getting a error on uploading a avatar thats bigger then the dimentions set...

Fatal error: Call to undefined function: remote_filesize() in /usr/local/apache/www/crazyapes/majorfmforum.com/htdocs/forum/includes/functions_upload.php on line 106

[magyosha]

could not get this working at all
always says the image is to large and makes no attempt to resize ..
checked and double checked all the editing that was needed ... (tryed with profiles & atachments)
running vb 3.0.3 with the latest security fix's applied

attachments stored in the filesystem .. but would not think this would affect the profile pic as they are in the dbase .. and they don't work either ..

[kall]

Parse error: parse error, unexpected T_ELSE in /home3/nzboards/public_html/forums/includes/functions_upload.php on line 341

That's just trying to upload a gif larger than the dimensions. Same thing happens if I use jpg.

[kall]

Possibly a typo? Could you post that line and I can compare?

[givemeplain]

Hey, this works well for me .. but is there a way so that when an image is reduced in size, you can click on it (in post) to view it full size in a new window or something? Thanks.

[MrNase]

As an update I've completely removed this hack, thenreinstalled itusing the current uploaded files and it worked with 100%success foravatars and attachments. I tested large jpg, png and gifimagesfor the attachments, no errors, no problems. That's withvBulletin3.0.6.

Thank you very much. I updated because some members reported errors which I never got. I really hope these are resolved now :)

[John_44]

Very nice Hack !
Unfortunatly it doesn´t work for me. No errors until i upload a larger Image -> Then it says Error 500 -> could not execute Script. I´m using the German Provider 1&1 and would apreciate every help possible.

(GD Lib is installed)

[John_44]

No, it always hapens.

[John_44]

Ok, i played around with it. Please notice that i know nothing about PHP, but i was able to track down the Problem:

If i change:

if ($width_factor > $height_factor)
{
$nw = round($w / $width_factor);
$nh = round($h / $width_factor);
}

to:

if ($width_factor > $height_factor)
{
$nw = 400 ;
$nh = round($h / $width_factor);
}

it works. 500,600,1000 -> Anything bigger 400 don?t.
I guess that for some reasons ImeageCreateTrueColor don?t like big numbers.. but i have no Ideas why.
The image i used was a Standart jpg with 1600*1200. Size played no role.

I would really apreciate your help on this topic, as i will definitly extend this genius hack !

What i want to add:
-Other extension (.jpeg,.jpe ...)
-File size

Does anybody know if GDlib can read EXIF Data ?

(Yes my English sucks ;))

[John_44]

Sorry. It works with 450 and 500. But 600 is to mutch. This makes me sick.

(And it is not "ImageCopyResampled". The following line works just fine:

ImageCopyResampled($ni,$im,0,0,0,0,1000,$nh,$w,$h) ; )

[John_44]

If somebody else has the same Problem: As a workaround i use:

$width_factor = $w / 500;
$height_factor = $h / 500;
if ($width_factor > $height_factor)
{
$nw = round($w / $width_factor);
$nh = round($h / $width_factor);
}
else
{
$nw = round($w / $height_factor);
$nh = round($h / $height_factor);
}

$ni=imagecreatetruecolor($nw,$nh);
ImageCopyResampled($ni,$im,0,0,0,0,$nw,$nh,$w,$h);
UnsharpMask($ni);

[John_44]

And i found a Bug: If more than one Image is resized, the script returns an error 500. However the first one is still uploaded.

Anybody else with this error ?

[nosaj]

thanks mini2, installed and working on my vBulletin Version 3.0.7 Forum. :classic:

[LiewCF]

Great! this hack work for my bloggers forum (http://www.malaysiabloggers.com). There is other similar hack too, but it does not work. :)

Thank you!

[JohnBee]

I started to install this hack on 3.0.3
but in the functions_file.php I could not find the section that says:

@unlink($attachment);
eval('$error = "' . fetch_phrase('attachbaddimensions', PHRASETYPEID_ERROR) . '";');
$errors[] = array(
'filename' => $attachment_name,
'error' => $error...

is there another portion of code I should look for?

[Blam Forumz]

for attachments is it possible for them to be clikabkle?

[Harley D]

No idea on the darker image, I cant reproduce the problem.

I have a PHP Store that has pic resizing, and I've found that gif, jpegs, and pngs.... one of those will darken when resized. try changing the type of file and upload it to see how it renders after being resized.

[Harley D]

Hello,

first, thank you for this nice hack. :)

But, I have a Problem. :disappointed: The uploaded picture is "darker" than the original one.

attachment 1: original
attachment 2: uploaded in my forums

gd version: 2.0.12

Can you help me? :ermm:


I did some more checking and found that .JPG will darken but .GIF doesn't.
So use paint shop or photo shop to change from a JPG to GIF, this should solve this problem. If it does, please post so other will know if it works.

[Razasharp]

Excellent hack! *clicks install* Does exactly what is says on the tin :-)

Just a quick question tho, do the 'original' large files automatically get deleted off the server or do we have to do that manually?

Also a note for people using the attachment resizer, you have to 'increase' the sizes in your ACP to let the larger files get uploaded to then be resized. :-)

[Razasharp]

Sometimes the images shown (JPG) are a bit dark... anyway to get them lighter? :-/

Most users wont know how to conver to gif, so thats not any option really...

[Bounce]

Uploaded all as per instructions,doesn't seem to be working

Do you need safe mode turned off for this to work...

Uploaded the 2 hacks,no errors or anything but doesn't work :ermm:

Edit: Got the avatar hack working,slight problem same as another user, the pic is slightly darker :rolleyes:

[lionslair]

Thanks for that wiked hack

[kobescoresagain]

anyone know if you can intergrate this into vb gallery?

[kmike]

Excellent hack.
I see a couple of small problems with it though:

it doesn't handle additional image types supported by getimagesize() PHP function, e.g. .SWF, .PSD, and .BMP. First two are probably non-issue, but our forum has .bmp attachments enabled, and this hack will generate an empty resized image for them
a huge image can cause "out of memory" PHP error on ImageCopyResampled() call, and the hack doesn't handle these situations (I think 500 errors cited in this thread are caused exactly by this - check your error logs for PHP errors)
the attachment file size stored in the db is wrong - the stored number is the size of original attachment, not the resized one. the total space occupied by member's attachments will be wrong, which may cause problems if attachment quotas are defined for usergroups
some memory could be freed during script execution by adding ImageDestroy() calls in the proper places
I think UnsharpMask() call is only needed if the attachthumbs option in admin CP set to "Yes - sharpen" (to be consistent with thumbnails handling)
there's no need to mess with "require_once('./includes/functions_image.php');" line at all. The file is only included once, if needed


I've fixed these problems, and also did some code cleanup.
You can uncomment error_log() lines and change email to your actual address to get some idea how this hack performs.

kmike,

nice fixes. has anyone tested this yet on 3.5 RC2?

[thephonemall]

I am getting this error when attempting the Profile Pic modification:

Fatal error: Call to undefined function: unsharpmask() in /home/website/forums/includes/functions_upload.php on line 294

EDIT:

Nevermind added
require_once('./includes/functions_image.php');
and it works!

[MrNase]

Can this one please be ported to vB3.5? :)

[lazytown]

A port to 3.5 would be VERY useful.

[wildondallas]

has anyone tested this yet on 3.5 RC2?
I have tested this hack (Geek Auto Avatar Resizer (https://vborg.vbsupport.ru/showthread.php?t=78287))with the 3.5.1 upgrade, and its working perfectly so far. Only tested with IE though...See my post and screenshots here: https://vborg.vbsupport.ru/showthread.php?p=831196#post831196

[ConqSoft]

As I noted in the other thread, 3.5.x has built in Avatar and Profile Pic resizing, so these hacks are now obsolete. ;)

[sgtmaj]

I still have yet to find a hack that will automatically resize attachments for version 3.5.xxx.

Anyone know of one out there????

[Raydar]

Hi,

Can this hack also be used for VB 3.5.3?

Thanks

Reg

[mrcake]

It's gone. :(
Anybody know if there is a new one that resizes automatically? users are whining... lol
