Component skin question

Is there any way to change the skin of a TileList component with the skin changes appearing ON TOP of the source image? I want to take some basic images from my TileList and make the skin so that it appears to be in a film strip. So I want to change the TileList or CellRenderer skin so that it looks like a film strip.

Any way to do this? if so, how? any change I make to CellRenderer skins appear BELOW my source image!!! HELP!!!
