Including visual resources in your project or paper will add richness and texture to your final product. Examples of visual resources include maps, photographs, graphs, charts, drawings, cartoons, tribal symbols, artifacts, etc.
Scholarly articles/books don't always have a ton of photographs but they often have graphs, charts, maps, etc. that can serve you well. Also, organizational websites, blog posts, etc. can be good sources of images. Whenever possible, remember to cite where you found the image.
