I've tried everything I can think of but I can't get Shopkin's minion overlay to work. Normally I just put all the images into one background but I decided to try something new and use a premade base so I'm kind of lost. Can anyone help me out?

This should work.

img { height: 0px; width: 64px; padding-bottom: 64px; padding-top: 0px; background: url(URL) left top no-repeat; }

It did! Thank you so much!
