I would love to see an application that aggregrated all of the pics I send to twitpic and put them in a rotating flash gallery I can embed on my blog, myspace, facebook, whatever. when I send my pic up via email, I would assume contextual ads could be pulled from an ad database and unobtrusively placed within the context of the image to generate some revenue. Putting all of my pics in one place would make for a nice visual on my site or social space. Add commenting that was within A central app, so the comments followed the branded image viewer wherever it went and we may have a business model…
