I use a lot of Simply Yin templates as I love edges around my photo's. On the templete layout I click on the object, box, circle that I want my photo to be placed into. I find my photo and drag and drop it onto the template. I hit Ctrl G and what that does is place my photo inside the shape and now I can resize it to fit the object they way I want it to. I hope that helps. There may be an easier way that others might now but this is what works for me.
I hope that helps.
