Handling .ico files in media sources

[MaticSulc]

MODX 3.0.3-pl, PHP 8.1.17.

When adding a favicon.ico file in the website root, media source preview doesn't work for it and it keeps filling the error log. PHP warning: exif_read_data(favicon.ico): File not supported

I can simply make the mediasource ignore it, by adding it in the skipFiles setting, but since .ico isn't under imageExtensions, I don't expect it to generate a preview. Can't replicate this in MODX 2.x.x.

It generates a preview because the string 'image' is in the mime type.

The same PHP warning occurs also for other image types (like e.g. PNG or WebP) when PHP 8 is used. Probably the code has to be changed here, to run exif_read_data only for image types that support it.
