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,

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!

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.
