Game face generator wont generate

I am trying to make my gameface on the website. I took the pictures, I uploaded them, I resized them, I put the pointers where they are supposed to be and when i press the generate button it gives me a load screen for a few seconds and then it hits me with "There was an error uploading your photos and generating your Game Face. Please try again." 

I have attached a printscreen of the problem. 

Any advice?
