Hmmm, seems much the same as catbox, except that you need a click more to get the image link but gives you more options in return.

What I'm really interested in would be a (preferably) self hosted solution which allows one to share either single images or albums with visible (but non-obscuring) labels, and where one can easily flip through images in an album. Also needs batch upload (can be by FTP, the method doesn't matter much). I've tried Pixelfed half a year ago, and while I really wanted to like it, it didn't really have proper albums and labels at the time.

Hosts like Postimages and Catbox are fine, I guess, much like Discord is "fine, I guess", but I don't want to spam the host by uploading an image 50 times for 50 different posts, and no way that I'm gonna check all previously uploaded images whether I've already uploaded the one I need.
