iPhone app? Photos?

[His_Dark_Half]

so I usually frequent barter town forums so I can join in on the RP fun. But I can't for the life of my figure out how to post a picture from my iPhone app. I'm usually too busy to hop on the computer for more than a few minutes at a time and it would be a lot easier to do from my phone if I can figure out how to post pics from my phone. Any help is greatly appreciated.

Images must be uploaded to an image hosting site and the image URL must be used inside the IMG BBCode tags like usual. There's nothing special about the app.
