Separate Background Images by Layer?

I’m working on modeling an M4A1 Carbine, and I’m building it in separate parts, one on each layer. What would be really handy is to be able to have my background images separated by layer, so, like the objects in each layer, the background images can be seen or hidden according to which layers I have selected at the time.

Is there a function in Blender that can do that? Because I haven’t found a way to make it work, myself.

You could if you use the Empty as Image , and line up your Empties to display in relation to each other - then you can put each correspoonding image as an empty on the layer with the part, and just switch layers with the number keys on top of the keyboard.
