I love it when EXIF information is in the images. For instance, you can find out the date the picture was taken. In this case it was:
5/18/2004 - 12:06:28 - 0001
5/18/2004 - 14:58:01 - 0156
So basically this entire set was shot over the course of 3 hours.
If you are into photography at all (I am), then some of the other information is interesting as well. ....
