Selected EBSCO databases include a Image Quick View search option. Selecting it lets you search for journal articles that include images. You can limit your image search to types of images: black and white photos, color photos, graphs, charts, maps, diagrams, or illustrations.
EBSCO images are copyrighted by the articles' publishers. While the images may be printed for personal, non-commercial use, or used in presentations in non-profit educational settings, they can't be posted on websites or used in any other form of publication or mass media without written permission.
