I've been uploading to the gallery here and it's quite convenient in a few ways. I can just upload a batch of photos to an album and use them in threads as, and when I want them.
So when I've sorted and edited a batch of photos I can upload them to an album or albums then create threads as I get time to write them, or have my pictures on hand to post in any comment I am writing.
At first it seems cumbersome but once they're uploaded you have them at hand wherever you are and whatever device you're using and you know all members will be able to see them, 3rd party image hosting is one of the worst thing about old forum software, Facebook should be very grateful for that system, it crippled their competition and led to their rise in power!
