3D Effect Quick Tute

This is just a quick tute for an idea for a 3D effect. First you will need some transparent gif images. For this tute I'm using these 3 floral images.

Composite these onto a white background as you like. I made this image.
Then I put that through the Deco Tool and clicked sunk and put a white frame on it to get this image.
Then I cropped and composited parts of the flower images back onto that image so that they appeared to be coming through the frames and got this image.
