This website has an abundance of royalty-free material available. The material resources offered range from photos, illustrations, as well as video clips. This website could best reach a wide-spread audience from K-12, and I mainly say that due to the variety that is offered. Also, there is an option to search by photographer or artist. So, if there is a particular style of art or artist that an educator may be most supportive of, or comfortable choosing work from, this will help filter out all others. The photos are arranged in a form of galleries which makes searching for photos much neater and concise, and the price range is from $2.50- $10 depending on the size. The qualities of the resources are superb. They contain great color quality, photo/video aspect, and variety.

This website is of the form of a blog. The material itself is a collection of royalty-free photos. Mostly, I could see these photos reaching a mature level of students in grades 9-12. I also think that these students would have a less difficult time finding resources that they would actually be able to incorporate it into an educational setting. The photos on photos8.com are priced at $5 each. The quality of the work that can be found through categories and sub-categories are well worth the price.

This website is a government site, so it is a public domain and provides all resources including photos, videos, animations and podcasts for free to the public. The acronym USGS stands for United States Geological Survey, which means the photos and resources on this site pertain to elements of the geologic structure in the U.S. This site would be useful for all audiences of school age in grades 4-12. I chose that range because with the real-life depictions of our country's geography, it could easily bore and audience that was any younger. They are excellent quality resources and precise photography at our disposal for nothing out of pocket.
