Yeah, this was my first thought. How many slightly older, no-longer-being-updated pieces of software will fail to open the new version? Hopefully it’s built in a way that it just falls back to legacy and ignores the extra information so you can at least load the file.

    I remember the Wild West Web days when it was a toss up seeing if animated Gifs, transparencies in images, or the specific hexadecimal for your personal shade of purple you created would render properly between browsers.

    I mean, that's already how animated .gifs work. If somehow you manage to load one into a viewer that doesn't support the animation functionality it will at least dutifully display the first frame.

    How the hell you would manage to do that in this day and age escapes me, but there were a fair few years in the early '90s where you might run into that sort of thing.

    Probably most notably the iOS photos app until like 2014.

    Edit: just checked. iOS 11 in 2017 added gif support to photos

    I’ll also add, safari supported animated gifs for a long time before that and you could still save them in safari like any other image. But photos would only show the first frame like you said. When 11 came out they played like normal.

    One example is piefed unfortunately. Animated gifs as avatar or banner don't animate currently as far as I can tell.

    Those are displayed in browser, right? The only reason that would be happening is if Piefeed is recompressing images and their code is not smart enough to identify an animated .gif and act accordingly.

    Yeah in browser. I should probably open an issue ticket if nobody else noticed yet.

    Relevant issue: https://codeberg.org/rimu/pyfedi/issues/665

    tl;dr - it's an issue with the pillow image library in python. It's on our radar though. I got posts working, but you have to click through, the thumbnail still isn't animated.

    Oh good looks like you're on it already nice! The only other thing I noticed missing moving from Lemmy was sorting Top by "x" amount of time, but I see there's an open issue for that as well already. Nothing for me to do lol.

    Still lots of things to do :)

    Lemmy has been at it for years at this point while piefed only started up a bit over a year ago I think? In any case, I have only been a contributor for maybe a couple weeks, so lots of catching up to do!

    I'll bet you a shiny penny that's what it is. The backend recompresses things to some other format, probably a low bitrate JPEG, in order to save space and/or in case some joker uploads a 90 megabyte uncompressed TIFF image to use as a profile pic, or something.
