Oh, wow, that was exactly what I needed. Thank you. I have used several programs like this one and for some reason I couldn't find that button.

I just downloaded this program and I hate to post such a simple question. I feel like I am missing something. Maybe I didn't search hard enough for the answer here. I am trying to put multiple pictures together, kind of like a collage. So, I want to put them on different layers but every time I open another picture it puts it on another canvas page. So, yeah, how do I put pictures on the same canvas page but on a different layer?
