Royalty Free simply means once you buy the image, you no longer have to pay royalties on that image (unless you use the image in a way not originally agreed upon). Although FREE sites are the best way to go, sometimes you just can’t find the right image for your project, or you want to sell a product that has an image on it – that’s where royalty images come in. Here are several sites that sell imagery. Some are subscription based sites, others are per image based and some a combination of the two. Many of these sites give away images every month or even every week. Subscribe to their newsletter to get FREE images and discounts.
