Now that AVIF is available in the forum, I thought it would be great to be able to select that format for the thumnails that the forum generates from the provided images.
It would be great to be able to select avif for the photos that are uploaded and need compression due to exceeding forum stablished limits.
AVIF is a great format that shines when you need strong compression.
Main web browsers and mobile browsers support it (the only exception being MS Edge, but it seems next stable release will provide it).
For the forums that are conservative and need to work with old browsers, giving the option to select jpeg as compression would be great.
In my opinion, by default, the forum should maintain the original jpeg format, but give the admins the option to select jpeg of avif for all thumbnails and converted images.
A parameter to be able to control the degree of compressio for the authomatic conversion would be greatly wellcome.
If it where able to detect when a browser does not support AVIF and serve a jpeg image on the fly it would be great, but that is not an easy task, and may be not the philosphy of the developers.
I take this opportunity to congratulate the developers for implementing avif support, I have tested it and it works very well.
