Help with picture overlay script if you'd be so kind.

[Keybit]

Could anyone please help solve an issue I'm having whist trying to put together a little webpage to allow (a facebook) group members to easily be able to generate personalised "The Group™" profile pics!

I feel I'm soooo close but i believe i need to auto resize (and possibly crop) to a set size (the same as the overlay) the uploaded pic before the overlay does its work which will solve the issue of the overlay sitting too high or low (depending on the size of the uploaded picture)

You can take a look at the progress thus far at the following link..
The Group Profile Pic Maker - If you dont know, get to know!

Just need to iron out this bug then I can make it look a bit more attractive!
