.webp too ok.

Oh boy I gotta implement a reply feature, and a notification for the replies, this is already hard to keep track of

Yeah it has some security built into it from the framework by default and I don't want to bother allowing "obscure" file formats just for the sake of allowing anything - but I plan on "normalizing" the file formats so when you upload it is served in a common format (while also allowing you to download other file formats for your liking)

You cant do gifs or videos right now buts that's on purpose, repost engine only works for images, and when I allow videos and gifs they'll have filters so people can filter images only, gifs only or videos only

I also tried SVG, which you don't accept. thats probably a good idea.
