This is how they look on Damus though.
But still they play.

Pretty cool shortcut for GIFs. Now I just need to pick the top dozen GIFs I use often and add them to my custom library.

That would be image specific, not feature specific. Damus needs to add better support for those image blobs I guess.
I think It’s a mix between Amethyst picking an obscure type and Damus not rendering g an obscure type. 🤣
It's this very specific image. It was a image without a file extension, most likely encoded as a webp. Will Damus show animated webp "GIFs"? Or does it need to be an actual .GIF file?

I never looked exactly what I’ve been sharing 😅
