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 ;))

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) ; )

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);

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 ?

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

Great! this hack work for my bloggers forum. There is other similar hack too, but it does not work. :)

Thank you!

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

is there another portion of code I should look for?

for attachments is it possible for them to be clikabkle?

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.

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.
