Becaue the locations of the slotted gaps may not line up adequately with all photo subjects, not all photos are suitable for printing on this product. Scenic photos work best and for group photos, quite often a gap will line up with someones face. For other photos that have an obvious important subject, we will do our best to give an "estimated" sample proof of approximately where the gaps will line up for you to approve before printing. Please keep in mind before you decide, that we are unable to guarentee exactly where the gaps will line up, only approximately, within about a 1/4".
