Wow, here is a nice source for some basic stretching exercises:

They have a basic and advanced stretching routine. I don’t agree with “advanced” routine because it is just a small variation of the beginners stretching. Hoverever, it is a nice source with photo samples for novice and intermediary flexibility training.

I will post my own stretching workout with some more variations and advanced stretching positions sometime next week (Photo manipulation takes a lot of work :)).
