Turn your photographs into cash via sites like Fine Art America, which lets you upload your images to sell as prints, t-shirts, phone cases and more.

I have been thinking about going into Affiliate Marketing for a while now. I know it seems easy, but really is not. That is why I have yet to do it. I know it takes quite a bit of traffic.

I am making a pretty decent amount of money already. I just hope it stays that way. :]
