I just upgraded a system to 3.57 (I know, I'm a little late to the party). After doing so, I went to upload a logo for them that was in GIF format. After selecting the file and clicking on Upload, I received the following error:
imagecolorsforindex(): Argument #2 ($color) is out of range in /home/folder/public_html/cmsAdmin/lib/image_functions.php on line 152.
Rather than trying to diagose the issue, I simply saved it as a JPG and the upload was fine. I have to say, we have not had a gif in years, so I'm not sure if it just started happening or not. It could be mere coincidence.
I just wanted to report it in case there was something anyone know about it.
We are using PHP 8.1 on this site.

Hi Gary,
Thanks for the report. It looks like this is a new issue introduced by PHP 8:
From: https://www.php.net/manual/en/function.imagecolorsforindex.php
imagecolorsforindex() now throws a ValueError exception if color is out of range; previously, false was returned instead.
If you still have that GIF available could you email it to me at dave@interactivetools.com? We'll try to reproduce the issue and add some code to workaround it.
Thanks!

Hi Gary,
I've found a fix for this bug, which should be included in the next CMSB release version. If you'd like to patch it in the meantime, you can replace this line in cmsb/lib/image_functions.php (at/around line 152)
$transparentColor = @imagecolorsforindex($sourceImage, $transparentIndex);With this:
$transparentColor = false;
if ($transparentIndex >= 0) {
$transparentColor = @imagecolorsforindex($sourceImage, $transparentIndex);
}Let me know if you have any further questions!
Thanks,
Technical Lead
