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

i get this error

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

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

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.

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?

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