Pastebin like service for photos

Looking for something that lets me upload photos to paste into forums and the like, mostly for support or to show others. I'd like to embed in the forum or provide an ad free way to view them. It would also be nice to have an account that stores these images over time so I can reference them later. Dropbox didn't seem to be able to do this the way I want. Does anyone know of anything like this? Thanks.
