Just read my own post and I think it needs a little explaining. I wrote 
it for myself so it has no comments. Not my normal style when sharing 
code. Anyway...

The first three assignments determine how the program will run and what 
it will do. Here is what they mean:

$testing = 0; # 0 = doit, 1 = just tell me what you would do
$fromImageDir = '...'; # this is the directory where your pictures reside
$toImageDir = '...'; # This is where your pictures will be moved (i.e 
not copied)

The $toImageDir will be a base directory. In it directories will be 
created in the format:"YYYY-MM-DD". For example "2009-01-31". The 
pictures will be moved into the directories that match the day they were 

I also notice that you asked for a GUI that your wife could use. I 
missed that when I first replied. Maybe, you could set up an icon that 
evokes this script. If your input and output directories are always the 
same that could work for her. If you need to update the input and out 
put directories, this may not be a good solution.
