I thought I'd pop by and throw my suggestion here, I think there should be some sort of mobile upload solution. It might sound a tad odd, but some people might actually use this feature, I know I would.
There many ways to do something like this, one of them being like twitpic.com. A user is given a "secret" email address ([email protected] for example) and they can attach an image to the email and send it, they will recieve and email back saying "Click this link to edit the picture (link)" and thats it.
An alternative option would be to have an [email protected] where people can either, just send pics then get a link to edit them with.
Thanks for reading :D
