The niche interest groups are what I miss from reddit - I'm out of the loop for several things now I don't lurk in the respective subs any more. I think I'll start using their RSS feeds so I don't miss out too much.
Memes are just easy to consume and upvote, so I understand them becoming popular. I've got multiple duplicate accounts with different communities added/blocked so can get the memes only when I choose.
No, it's just that @[email protected] didn't give the full link. It's happy and healthy at https://letterboxd.com
You can add a title and description to images, folders, albums (what we've been calling folders), sub-albums, etc. You can search on those, but it's not a structured thing like tags. I guess you could just store some JSON in there but you might need to get smart with your queries to search. Afraid I have no idea if there's plugins, or even if what I've been using is a recent and/or unmodified codebase.
I think it's more designed for photo uploads, as there's an option to keep exif data, and it automatically makes images of different sizes (including your original, maybe massive upload).
What features are you looking for? As others have said, if you just want somewhere you can store images yourself, you don't even need software aside from a webserver and something to upload with.
But there's also things like user accounts, tagging, browsing/discovery, plus whatever else gfycay does/did.
Anyway, just to actually give you a suggestion, chevereto is used by a friend and it's a lovely user experience (can't tell you about the admin side, though). [edit: This uses folders to organise - no tagging - so it might not meet you needs, which is why I was asking.]
As noted, this is an old article. You can install the plugin here: https://addons.mozilla.org/en-GB/firefox/addon/firefox-translations/
I just tried it on https://www.tagesschau.de/wirtschaft/technologie and it's definitely good enough to be usable, although it has translated the top story as "What the new data glasses from Apple can". Google Translate's version is almost the same for most of it, although it gets "can do" right.
It initially recognised that it could translate feddit.de but seems to have stopped now. Hmm.
Anyway, even though German->English is a pretty easy test given that English is a Germanic language, I'm happy to leave it installed and test it in the wild.
Arguably, the fix should be to "it" since anon is a utility account, not a user.
