So like I said, I needed to make a Facebook cover image at a specific size of 851 x 315. I created a canvas of 851 x 315 to get started.
The images I'm using to make this are straight from my camera so they are obviously way bigger than that.
I want to play around with adding 2 or 3 photos into Paint.net and then be able to independantly move, zoom, etc them until I get it just right.
I might put in photo 1, put it where I think I'll want it and then add in photo two. After setting photo 2 in place I might realize that I need to zoom a bit in or out or photo 1 to a new spot. When I tried that now, photo 1 had been cropped to where I had dropped it after the initial placement and I now had no way of getting back to the full image that I had pasted in.
If that doesn't make sense, let me know.
