What is that supposed to be for?
Try copying everything then masking each piece seperately.
You will have to copy the image and mask each image individually. So the red shape will mask the original image and the green shape will mask the copied image. Then you can move them around and do what ever you want. It does however increase the file size if you embed the images when you save the file so keep that in mind.
Call me tonight or will you be home Friday? I can come down for a bit and help ya out.
