By the Book

To get the best results for the picture directory:

1)  Use the same camera for the pictures
2)  Make sure the family pictures are landscape
3)  Make sure the aspect ratio is 3/4
4)  Do not use cropped photos

If you have entered a description underneath the picture that is extremely long or the family is quite large (say 10 children), this can cause a mis-alignment of the pictures in the directory.  Try entering something shorter like "The Smith Family" instead and see if that doesn't fix the problem.
