Definitely consider self-hosting for file sharing, because public file sharing sites without restrictive file size and auto-delete limits get abused and shut down constantly. 0x0.st (mentioned in another comment in this thread) used to host files indefinitely but switched to a temporary system because of abuse, so anyone who used it as their file host will now have a mass of broken links. Unfortunately, none of the self-hostable file sharing options with thumbnail previews that I’m aware of support image albums which was the most useful feature of Imgur.
