I want to create a collage of pictures in Photoshop and I am running into a minor annoyance: every picture I drag into my work space becomes its own layer. This makes it very annoying to move pictures around, I have about 30 of them, so I cannot even remember which picture goes to which layer. It becomes a guessing game to find the layer to select to actually move the picture. Isn't there any way to either have all the pictures in a single layer or else so that when I click a picture, it automatically selects that layer and allows me to adjust/move it?
