iStockPhoto is just one site that allows you to sell stock photos; there are others. Before you decide to go crazy and upload your whole album, take note of what’s selling well and try your hand at doing something similar. iStockPhoto also works for those who know how to render images; some of their most popular images were created on a computer! Have three killer stock photos ready for iStockPhoto’s inspection; they will want them when you sign up.

mTurk: I personally like this one for some spare cash. It does not take much to earn $20 a day. Some claim that they are able to make a living by dedicating their time to different jobs at mTurk. You will have to go through a learning curve, but once you get comfortable, you will find plenty of good and interesting HITs (Human Intelligence Tasks) to work on.
In your parent's day, the only way to make a living drawing comics was to get your comics into the newspaper or work for DC and Marvel. Today, you can draw comics about anything you want and start your own site to host them with a little money borrowed from mom and dad. Selling t-shirts and space for advertisers is a great way to earn a little money with your own comic.
