Love services like this, but the problem is convenience. I've been using droplr and/or cloudup for years. Their mac apps make it stupid simple to share just about anything.
Another problem: I can't abandon cloudup because they act as my archive ... my "dropbox".
How I see it is: you're not really in the "Make image sharing stupid simple", you're in the "make it easy for people to switch" business.
Solve those two problems and you'll have my business. :)
