If you want to buy personalized children’s books for someone, and all you have is a hard copy, printed picture.  Will that work?  The photo will work if it is a high quality photo.  It needs to be a close up picture of the child without being fuzzy.  If it appears fuzzy, when it is scanned in and blown up larger, it will get much fuzzier.  If you keep all of these things in mind while choosing your photo and understand that the book is only as good as the picture you provide, then you will be happy with your selection.
