AVIF support is not available in your version of PHP, since Kirby Update to 4

Kirby 4
7

I’m having the same error in a similar scenario. I also updated from Kirby 3 to 4. locally avif is generated but once I upload to my server images are not generated and on right click opening the image in a new tab I get the “AVIF support is not available in your version of PHP” error.

PHP 8.2 is running on my server locally and with my hosting provider. Just to be sure I contacted my hosting provider and they told me IM and php 8.2 can be used for avif.

when i check php info i don’t see any mention for avif in GD, only in IM

GD Support 	enabled 
GD headers Version 	2.3.0
GD library Version 	2.3.0

for now i just changed the order in my responsive image snippet (based on the responsive images guide), so i’m just not using avif. But If I want to use avif, from what I understand I need to change from the default GD to IM as a general image engine. (How to switch from GD to ImageMagic as image engine?)

c::set('thumbs.driver', 'im');

could tell me where i would plug that line into my config.php? that would change the engine for all image generation to IM? from what i understand at least for thumbs() IM is already the default?
