Selling photos online is a quick, easy and potentially rewarding way of making money. 
Some websites will pay you every time a photo of yours is downloaded or sold. It is up to you to make the judgment on which route to take. If you are a photographer you would be best to go the pay per sale route. If you’ve just got a few shots which you think people might want to modify or hold onto, you should go with the pay per download route. I am guessing that many people reading this will likely not have professional photography skills. In which case, try to gather up pictures which are rare, old, of some significance or of something famous. Keep in mind that if you’re taking photos with people in them, you get permission to put their picture on the internet. Some photo websites will require this.
This is a relatively simple and easy way to make money. It will likely not bring in high profits, but the effort it requires is low, thus I highly recommend it.
