Hi Alissa,

Your question about putting a matt below a photo. I may have my picture in my workspace but usually start out with a background paper or blank page and paste my photo onto it. You will now have 2 layers, a background and a picture. You can create a new layer and drag it between the background and a picture. You can put a piece of paper on it and manipulate it to look like a matt, or, make a selection around the picture and fill it which will create a frame. I hope this helps, I'm primarily PSP, I do use PS also, however, my language may be a bit PSP accentric, but I think the layers work very similarly.
