Images or illustrations can enhance your papers and presentations. Like written sources, images also need to be properly cited. Always indicate, or cite where you found the image.
Citations can be formatted according to the citation style you are using (MLA, APA, Chicago, etc).
Using images you did not create requires a citation in all cases. Citations should be accessible in the context of the image's use and should link back to the original image whenever possible.
No matter where you get your image (Google image search, ARTstor, WGSN Fashion, museum website, scan from a book) or how you use it (Power Point, in a paper for class, a flyer) you MUST provide a citation for every image you use. This is as simple as adding any of the known information about the work (listed above) to the bottom of the digital image. Provide as much information as possible.
The following image was downloaded from ARTstor. Here's the information provided by the metadata within ARTstor that I need to keep track of and include where appropriate.
