I was first thinking of reading all the directories and then picking  
one at random, then reading all the filenames in that directory and  
then picking one at random.  It would work, but it is slower (slow  
being a relative term).  However, I like Jacob's idea better.   
Keeping track of each photo in the database is helpful for many more  
reasons than just this one.
