Daphne, the pictures can easily be simple photos directly from your camera. Of course, you can edit them in PSP but you don’t have to. The size of the pages will use 2400 pixels wide images but if you have them larger, I’ll show you what to do. If they are slightly smaller, I’ll show you what to do. If they are really much smaller, you might want to consider a different picture OR make a collage with others, but I’ll also address that.
Hope it helps.
