I’ve recoloured my minion but I lost the code for the overlay. Can someone help me, please?

This seems to work for me... <style> img {height: 0px; width: 64px; padding-bottom: 64px; padding-top: 0px; background: url(INSERTURLHERE) left top no-repeat;}</style>

It works! Thank you!

Awesome, you're welcome!
