I was revising the tutorial on Mark The Dark and decided I needed some graphics.  Seeing that I’m cheap, I looked for free stock photo sites.  I compiled a list of the best sites I found.  These photos are great for using on websites when you want to fill up an empty space or even if you’re printing something.  Make sure you read the terms of use–their licenses differ depending on the site and the photographer.  Here’s the list (in rough order of usefulness):

Stock Exchange
Free Photos Bank
photocase
OpenPhoto
Morguefile
BigFoto
Pixel Perfect Digital
FreeImages
FreeFoto
Aarin Free Photo
NASA
NOAA
National Park Service
