Retain some control. If you upload photos of yourself, or friends/family with consent, it's worth going for the 'rights managed' licence option – otherwise you'll have little to no control over how your images are used (eg, you could star in an ad for haemorrhoid cream). See Alamy's page on understanding stock image licensing for more on the different types of licences.
Hey Dasjung . . . The Nike logo was bought for (I beleive) close to 35.00 from a college student. THAT is what is being talked about.

Just because someone isn’t trained doesn’t mean they shouldn’t be able to make money with their talents. The hard truth is training is not necessary to practice graphic design, just preffered, where as being a doctor REQUIRES the training. For EXAMPLE, I can go out into the world and become a manager of a business if I have the knowledge WITHOUT any training in the Business Management profession. Deal with it, Just because you have training in Graphic Design doesn’t mean that you and your peers are the only ones who can create a logo. Logos are one of those things that can either be elaborate (in which someone might come to you), or simple (in which someone might come to anyone who has shown the ability to do so).
Manage social media for businesses. If you have a knack for social media, you could potentially get paid to manage various platforms for others. Many businesses are too busy running day-to-day operations to stay on top of their Facebook, Twitter, and Pinterest accounts – and will pay someone with the knowledge and time to do it for them. To find these jobs, ask local businesses and check sites like UpWork.com and Problogger.net.
