If you are choosing to purchase 5x7 or 8x10 photos, please understand that those photos will require a crop, meaning that you will loose a portion of the photo.  The system will let you decide where you want the photo to crop at, but you will loose a section, top, bottom, left or right.
If you want the "full" photo, you will need to choose either the 4x6, 6x9 or 8x12
