Cool... any chance to see a "photo1x1.com" doing exactly the same for Instagram, maybe? (They favour square format creating a simikar problem for users).
I just skimmed the source code and it looks like you could add support for other aspect ratios really easily. Not sure if OP is accepting pull requests.
EDIT: I went ahead and added quick support for other aspect ratios myself. Feel free to use it.
