Green Screen in Premiere Elements


I was wondering if there was any way to lock the layer onto the background green screen image. I have a moving green screen object that I have filmed, and I would like to lay a photo over it, but when it begins to move the layer does not move with it. Is there any type of layer lock feature. Here’s what I am using:

Windows 7 pro
Adobe premiere Elements 8.0
Lenovo laptop


P.S. If I did not post in the correct thread please let me know. No need to scream. This looked like the correct forum.
