Watermark Attached Images

[filburt1]

This hack adds a watermark to attached images. The watermark, as specified by your own .png image, is added on image download, not when the image is attached. Requires GD2. Do not even try installing if you don't have GD2.

This could be useful to prevent people from using my site as a sig host....

Little child: How many licks does it take to get to the center of the install Button?

Old Owl: One, Two, *crunch*, Three.

Announcer: The world may never know......

/me licks the install button

[DPoole]

any image added to any website is downloaded using right click so how will this work then ??

`Save Image as`

[filburt1]

This processes the image sent to the browser in any situation. It'll always be there, and there isn't anything the user can do about it short of faking a file extension (AFAIK).

[jdmuniverse]

Thanks alot!!! I am going to install right now!! You're the best :D

[007]

Pretty cool. I'll try it out. :)

[jdmuniverse]

Hmmm... I cannot delete those 2 lines because they are not there... what should I do?

Here is my attachment.php I am using 229

[FFArmageddon]

very nice :)

*clicks install

[Mike11212]

question just to make sure I understand.
It doesn't add the watermark unless its downloaded?
or lets say if i have images enabled to view in threads would it show the watermark as well?

[assassingod]

jdmuniverse, I can see you code fine,
it's under:

header("Last-Modified: " . gmdate("D, d M Y H:i:s",$attachmentinfo[dateline]) . "GMT");


And please keep from posting vB files.

[jdmuniverse]

Oops, sorry bout that.... Is that the line I should delete?

Edit.. I see it now! Thanks!

[assassingod]

No, the code you are looking for is under that line i posted.

Grrr... I have GD2 but still after installing this all my attatchments show up as little X's...

Could it be that my .png file wasn't the right type?

[Magic Spark]

Thanks for this one, Filburt!

Great! ;)

[Velocd]

Awesome job filb! This should help with preventing people from hotlinking attachments (not that I think they can anyway, since .htaccess things I've applied).

[Mike11212]

can anyone tell me if this shows the watermark on every image or only when the image is hotlinked

[WEForums]

To my understanding, everytime the image is downloaded (viewed), you will get a watermark picture.I think (but don't quote me) it works for hotlinking as well as yoursite.

Anyway, how do you know if GD2 is enabled? Is there an easy way to find out? (I don't really know all the server details, I don't own the site/forum or anything.) Hopefully it's located somewhere on the site...

[007]

I found out by simply emailing my host and confirming it that way...

Email=good :)

Anyway, speaking of that I am using 2.2.9 and the code in attatchment.php is very similar.. Is that the reason this doesn't work for me? Has anyone else tried this in 2.2.9? What should I do? This is one of the coolest ideas ever and I can't use it :(

[jdmuniverse]

I'm having a small problem with gif files... the watermark shows all screwy :) On jpg it works like a charm though... Any ideas?

Heres a gif to see what I mean...

thanks again...

[Austin Dea]

Nice seat ;)

[jdmuniverse]

Not bad eh? LOL

[filburt1]

GIF support in PHP is generally horrible. However, I have a solution (which I don't have time to implement but anyone with GD2 experience can):

1. Load the gif using imagecreatefromstring
2. Create a new image via imagecreatetruecolor of the same dimensions
3. Copy the entire gif onto the new image
4. Destroy the original gif

The problem is likely a palette issue.

If thats the case I can't use this hack :(
a lot of people upload wallpapers to my site and the watermark would damage them.

[matthepepe]

fantastic hack filbert and probably the easy'st hack i have ever installed

*Mickie clicks install

thanks again

[007]

Anyone have problems with this in 2.2.9??? I can't get it to work and I do have GD2....

[matthepepe]

everyone thats posted so far w/ 2.2.9 is having a problem, im just getting red x's for my images when i install.

[jdmuniverse]

I have 2.2.9 and it is working fine... I had the same problem finding the code... read the first page and they told me where the lines were.

Delete the 2 lines below this...

header("Last-Modified: " . gmdate("D, d M Y H:i:s",$attachmentinfo[dateline]) . "GMT");

The only problem I am having is with the gif files.... which I described on page 2.

[matthepepe]

I did delete those 2 lines, and it still did not do me any good,

first i deleted

header("Content-disposition:$attachment filename=$attachmentinfo[filename]");
header("Content-Length: ".strlen($attachmentinfo[filedata]));

then i replaced,

if ($extension=="gif") {
header("Content-type: image/gif");
} elseif ($extension=="jpg" or $extension=="jpeg") {
header("Content-type: image/pjpeg");
} elseif ($extension=="png") {
header("Content-type: image/png");
} elseif ($extension=="pdf") {
header("Content-type: application/pdf");
} else {
header("Content-type: unknown/unknown");
}
echo $attachmentinfo[filedata];

with

$isimage = true;
switch ($extension)
{
case "gif":
$header = "image/gif";
break;
case "jpg":
case "jpeg":
$header = "image/jpeg";
break;
case "png":
$header = "image/png";
break;
case "pdf":
$header = "application/pdf";
$isimage = false;
break;
default:
$isimage = false;
$header = "unknown/unknown";
}
header("Content-disposition: inline; filename=" . $attachmentinfo['filename']);
header("Content-type: $header");

if ($isimage)
{
// watermark options:
$filename = "watermark.png"; // use a PNG-24 to preserve transparency!

$im = imagecreatefromstring($attachmentinfo['filedata']);
imagealphablending($im, true);

$watermark = imagecreatefrompng($filename);

$y = imagesy($im) - imagesy($watermark);

$w = imagesx($watermark);
$h = imagesy($watermark);

imagecopy($im, $watermark, 0, $y, 0, 0, $w, $h);

imagejpeg($im, "", 80);
}
else echo $attachmentinfo['filename'];


and i still get the red x's for images.

[007]

Yep, exactly. :( I'm going to try upgrading to 2.3.0 and see how it works then...

[S.Shady]

works fine but none of my attachments of images fully gets uploaded it seams

[007]

Ok I just upgraded to 2.3.0 and still nothing. :(

(Yes I do have GD2 and I have it selected in the options..)

[filburt1]

What exactly happens when you go to an attachment directly?

[matthepepe]

you get a red x.

[Courage]

I have attachments as files hack installed

Instead of


header("Content-disposition: inline; filename=$attachmentinfo[filename]");
header("Content-Length: ".strlen($attachmentinfo[filedata]));


I have:


header("Content-disposition: inline; filename=$attachmentinfo[filename]");
header("Content-Length: $filesize"); // attachments as files hack


I deleted header("Content-Length: $filesize"); , but I think that now i can add files without size limit checking ...

Ideeas ?

[007]

Yeah I now have 2.3.0 and I still have a red X. I contacted my host again to see if I really do have GD2.0+ and they said I do...

:(

[Skyline_GT]

How come I have this line header("Content-disposition: inline; filename=$attachmentinfo[filename]"); instead of header("Content-disposition:$attachment filename=$attachmentinfo[filename]");

[bitbender]

Where the heck does a fella FIND a good copy of gd2 for Red Splat ?? I want to use this hack, as well as watermark the pix outa the gallery (photopost), but I can't seem to locate a decent RPM for red splat 7.1 and 7.3.

Any Ideas any one ? All I can find wants tons of pre 6.2 rpm's installed as dependencies..

[WEForums]

I installed it out of curiosity, and this is what I get:

<br />
<b>Fatal error</b>: Call to undefined function: imagecreatefromstring() in <b>/home2/wef/public_html/forums/attachment.php</b> on line <b>89</b><br />

Does this, by chance, mean there is no GD2? Still haven't contacted the hosts... :oops:

[007]

Well I got a similar error and I contacted my host again and they said "Oh wait, we don't have GD2... we have GD 1.6 or something.." lol

*sigh* Anyway they are going to upgrade to GD2 and I should be fine then.

Try contacting them. You have nothing to loose by doing so..

Try contacting them. You have nothing to loose by doing so.. Yeah, just got to wait for the owner to get online. He doesn't deal with the forums (I do, obviously) and they are on a separate forum than the site...so got to wait for him to get on.

Doubt we have it since I got that error.

[wooolF[RM]]

]same here... jog works fine... gif = red cross :(
otherwise nice idea :classic:

[gmarik]

Soungs great. You're a real coder.

[007]

If a user attatches a copyrighted image, and my custom watermark is added to it, is this bad? Just wondering because this is an issue that could come up..

:ermm:

[Intex]

Filburt1 - any way this could be adopted to work with Imagemagick?

[Highlander]

and GD 1,6 or 1,8 is not working?

I know this thread is ungodly old, but I have a question:

How would I go about doing this? I am having the same problem, if someone could explain or give a code for me to add it would be great, I dont have any GD experience :surprised: :cry: Thanks! :)

*bump* can anyone help? :D

Ah ha! So that's why my other files do that! I was trying to figure out what hack did it and I guess this is it... anyone have a fix for this??

TIA

[PAINTBALLM]

Ok my stats page verifys that I have GD2, however, when I install this hack, images show up with a red X.

[glo]

Hi Paintballm,

I will guess that you have saved the image as CMYK and it need to be RGB! Or your location is incorrect.

Let me know if this helps!

[Rampag33]

Ok my stats page verifys that I have GD2, however, when I install this hack, images show up with a red X.

Proably means that you have the watermark image in the wrong location.

[PAINTBALLM]

will this hack be upgraded to vb3?

[joor]

Installed great and working, I do have a question though, I can't figure out how to make the watermark appear on the bottom right instead of left. Could you offer a bit of code for this? Thanks again for the hack.

*UPDATE* - Was having trouble with other files like PDF's not getting the right header info. I rewrote a few things and it works like I wanted, but I am not having a problem with GD or VB sending the watermark image as code and than refresh and it is an image again, back and forth. So uninstalling for now until I can work this out. 2.3.0 GD2 php 4.3.3

[Rampag33]

Great hacc, installed!

[alkatraz]

awesome hack! working on vb2.28

[kuska]

2.3.0 here.
Nice hack but a problem.
It corrupts every ZIP, MP3, TXT, BMP file thats uploaded.

Any ideas how to fix that?

[Skyline_GT]

hm.. how much it is not working for gif files?

[Skyline_GT]

THis hack does not support 2.3.0 and up..

[Gary King]

THis hack does not support 2.3.0 and up..
100%? There have been no filechanges to attachment.php from 2.3.0 all the way to 2.3.4, I'm sure of that. I don't have an archived copy of 2.2.9 or before, though :(

[juanchi]

could someone port this mod to vb 3.0.3, right now there is no working solution for vb 3.0.3, thanks to anyone that can help with this.
