I am guessing you could put the image in, then bake the clay on top and finish with a center of resin. It doesn't sound like that is what she does though, since she says it is not waterproof and I would think the resin would make it waterproof.
She might use a different resin though, like diamond glaze. Hard to tell from the picture. It is cute though. More juvenile than a regular cap.
