If you already have a website or blog, look for vendors that offer related but noncompeting products and see if they have an affiliate program. Stick to familiar products and brands—they're easier to sell. For promotion, place simple text or graphics-based ads in appropriate places on your site; you can review or recommend products or create a dedicated sales page or website to promote a particular product.
You don't have to be a professional photographer to sell your photos for money. People are constantly in need of high-quality, unique stock photography for websites, presentations, brochures, and so on, and are willing to pay for the right image. People generally search for images on stock photography sites like ShutterStock, Dreamstime, and iStockphoto by keywords, not by photographer name, so you have the same chance as anyone else of having your image selected. Just be careful not to post images of trademarked brands, copyrighted art, or people's faces that are readily identifiable unless you have a model release. Virtually anything else is fair game.
Blogger, which you can set up for free in less than five minutes, automates Google AdSense so that you can make money with your blog by displaying ads and getting paid when people click on the ads. To make more money, set up an affiliate program (see below) for books, music, and more, and insert your affiliate links whenever you refer to those items. A good strategy to set you on the path to success is selecting a unique topic, writing intelligent copy, and telling all your friends. You'll be off to a better start with a targeted audience.
Wow that’s a lot of very different kinds of topics you plan on covering, Rolland! My advice would be to pare it down to just 2-3 closely related topics that you can start to build an audience around… and from there, focus on just a small handful of activities that’ll help you attract some viewers/readers (rather than spending time on a lot of different tactics).
While it often takes a significant amount of time and hard work to build up your affiliate income, if you have the ability to regularly publish high quality content that drives in targeted traffic to your website, this online revenue source can become quite substantial. Follow along with my experiment growing a new blog, called SmartWP about WordPress, into an additional revenue stream for my business.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.
