Here are some of my photos on bigstockphoto.com - I haven’t uploaded that many yet, but I will be adding more in the future.  This should give a good idea of what kind of style of photography I use and what kind of photography works well to sell as stock photography.  Right now only my picture of the turtle and picture of rocks on the ground (for a texture) have sold.  So anyway, here they are! - bigstockphoto.com gallery

Also, if you are a photographer it’s free to sign up and you get $1.00 for every photo you sell.  Start making money of all those photos you take in your spare time!
