You might want to wait for iOS 6 and see how well the new iOS has implemented FB before you spend too much time on this issue. If you know how to do what you want on your computer, chances are the new implementation of FB will handle what you want.
I have worked out that logging in to f/b through the web I can't upload photos, but have down loaded the app for my husbands new account and this has a photo loader on the page , phew all this learning...........
