It's pretty cool that this just works now: opening a JPEG XL image directly in Adobe Photoshop. AVIF works too. Nice!

It looks like @discord fixed this, which is great news! https://t.co/8FkVKs6vxz

“Looks like @discord messed up, ruining (even retroactively!) many uploaded images: 1) they strip ICC profiles without color conversion, 2) they do low-quality lossy transcoding (q75 4:2:0 unoptimized libjpeg-turbo?), 3) recompressed images can be bigger than the originals. Ouch!”

The Cloudinary Image Dataset '22 (CID22) is now available at https://t.co/eCWswXcxWd
It is a large IQA dataset based on 1.4 million human opinions (gathered in 46874 crowd-sourced test sessions). It nicely complements existing sets like TID2013 and KADID-10k.

Transcoding uploaded images to q75 4:2:0 jpegs is also pretty bad. People use discord to share digital art, and until now they could share high-quality images as long as they're under 8 MB. Now those images lose a lot of quality, and not just the preview thumbnails. Very sad!
Stripping ICC profiles without conversion is a very amateurish thing to do. It's like a music score copying machine that removes all clef symbols and key signatures, saying "you don't really need those symbols, all music is in C major and written in the G-clef, right?"
