2) Creative Commons
Each of your articles should contain at least one image, but sometimes it’s hard to determine which image to use — it’s hard to find the time to design your own image from scratch. Stock images can be expensive, and who knows whether you can legally use an image from an ordinary Google search?
Creative Commons helps you filter and identify images that are available to use for commercial purposes, and modify to suit your needs. You can search popular sites like Flickr, Fotpedia, Google Images, and Pixabay for images. Just be sure to give the artist credit where credit is due!
