When I place an image into a template or another image and try to move image or resize it, program freezes. Then I have to close program & start over again. Why is this happening? Thank you!

Hey there, just started using Affinity Photo, and I cannot figure out how to drop an image into a phone case template that is at an angle. I know I how to drop image in, but than I have to turn the image to the correct angle of the case. Is there another faster way of accomplishing this? I've seen it done in photo shop so I am guessing there is. Thanks in advance, and attached is a image of the template I am referring to.
