Add image to layer
I wish to do the following and have not seen an answer anywhere.
I want to put photo A as background, put photo photo B as layer 1, then increase transparency of photo B.
I can create background layer, but if I create a new layer, select it, and then click on photo B,all that happens is that photo B becomes the background. If I try to decrease opacity of other layer, nothing happens. So how do I get photo B as layer 1?
