I think the solution to this is to allow people to provide a URL to an
image they have uploaded elsewhere on the web. Then we don't
have to worry about the size of the photo (although we will
recommend an ideal size), - any large images would be detrimental
to server performance if we were to host them.
I have concerns about the content of such photos too - we don’t want
the site showing inappropriate pictures, so I think this really would
need to be a pawn star only feature, to stop anonymous users adding
pictures which could get us into trouble.
