To add a personalized logo, you can upload the logo image to the Photo Basket at the bottom of the editor, and then drag it onto your main image.
You can do the exact same thing for a frame, but if you want to create a repeating image frame, the way to do this is by clicking on the Start tab > Shape Collage, dragging on the frame image from the Photo Basket and selecting an appropriate shape. You can then click Done! and then drag on your main image from the Photo Basket to center it within the frame.
