If you’re planning on placing a photo inside a frame, you can resize it in Photoshop Elements to match the exact dimensions without cropping off edges
Pick up the Recompose tool in Photoshop Elements and click and drag one of the transform boxes around the edges of the image inwards.
The new dimensions of your image are displayed next to the tool’s options, so you can match this to the size of the frame that you’re going to use.
Notice how the main subjects maintain shape and only the background elements are reshaped.
