I'm new to paint.net and I haven't been able to figure out the most basic of operations, working with layers. When I open a new image I get a background layer with that image. When I add a new layer, I get a transparent screen, layer 2. I want to import a new image to the transparent layer 2. However when I open the new image, I start all over with a completely new background image. How do I pull these multiple images together?
