[Pushed] issue with recount&rebuild in admincp

[Erikbe]

Hello,

When i try to rebuild attachment thumbnails it gives me a white blank page without any error message not even in the PHP error_log so to get a clue about what is causing the issue i open /admin/modules/tools/recount_rebuild.php and add the top i add

error_reporting(E_ALL);
ini_set("display_errors",1);

when i try again it shows me Notice: Undefined index: channels in functions_image.php on line 37

but i can't find what is causing the problem  help ....

I will, more likely to consider it as a bug.
channels is not a mandatory return value, specially for bmp, sometimes for png as well.

We need to place a fallback.

These errors (and others that don't cause serious problems on PHP < 8.0) should be covered by https://github.com/mybb/mybb/issues/4138
