A photo credit line identifies the photographer, illustrator, or copyright holder for images in a publication or on a website. The photo credit line may appear adjacent to a photo, as part of the caption, or elsewhere on the page. The photo credit line is the photographer’s equivalent of the byline for the author of a written work.
Publications typically have a standard format for the wording or placement of bylines and photo credits specified in their style guide. Photographers and copyright holders often require specific wording or offer suggested phrasing to accompany photographs or illustrations they supply. In the case of web use, linking to the photographer's site or another source may be required or suggested.
