I just went on the site and copied the pictures and then transfered those images to a micro SD card and put the card in to my LG Chocolate. I used the exact size from the site and it only clipped a little bit off the wings of the mini logo.

 

My Chocolate has a pic of a red car on it too, but it is not a MINI. Looks more like a Porsche or something - I dunno.

 

It might be the same one I have... It's distorted but it IS a MINI (I'm pretty sure) - the rear bumper looks like an Aero one to me, anyway.
