Thank you for your help. I understand what you mean but I cant quite figure it out. I'm ignorant as far as layers go, and I am unsure just how to start/open the layers. Also I am not sure how to make it transparent, or drag them into others. If you could give be a quick step by step, that would be awesome. I appreciate it. Thank you.
A layer is a basic building block of photoshop. I's really get a book or manual about photoshop. But quickly,have you layers pallet open (Window pulldown menu - layers) This will show you all the layers in your document. If it's a new document, you will probably only have the background layer. It sort of like dowing animation where you have a background drawing and then you lay clear plastic on top of it. So to get a layer on top of the background, go to layers on top pulldown menu and choose new layer. Now in your layers pallet you should see a layer on top of the background (this is a transparent layer). If you draw on it, you will draw over your background without effecting the background.
This is about as basic as I can make it. If you don't understand this, I'm afraid I can't help and you should by a basic photoshop book because you NEED TO LEARN THE BASICs before you can really start messing with layers.
