No. You'll get it if you look at my sig.

The way I cut Popcorn and Muffin's pictures as an oval, and pasted them to the signature background as an oval, without getting white corners around it to make it a square/rectangle. I know several softwares have this feature. Does PhotoShop have it too? *Cutting part of a picture as a circle*

Like in lovemyshiba's last signature that Amy made, the pictures of the pups were cut as ovals, if I remember. Maybe Amy can answer this question
