Summarize this article in one sentence.
If you plan to reproduce photographs in your work, assigning a figure number to each image makes it easier to refer to the photos when you discuss them in your text. Each image should have a unique number within your document (e.g., Figure 1, Figure 2, etc.). Once you have assigned a figure number and decided where to place your image in the text, you will need to label your image with a descriptive caption. The caption should include full information about the photograph, including the photographer’s name, title of the photograph, date, and information about the source. For example, in Chicago Style, the caption underneath a photograph could say: Fig. 1. Reginald Pepper, Still Life with Haddock. 1919, black and white photographic print. The Estate of B. Wooster. From: B. Wooster, Pepper’s Pictures. London: Faux Publications, 1932. Pl. 275. If you have obtained permission to use the photograph, you should indicate this in the caption. Write a line after the full citation in your caption indicating who owns the photograph and that you have their permission to use it. For example:  Fig. 1. Reginald Pepper, Still Life with Haddock. 1919, black and white photographic print. The Estate of B. Wooster. From: B. Wooster, Pepper’s Pictures. London: Faux Publications, 1932. Pl. 275. Copyright 1932 by the Estate of B. Wooster. Reprinted with permission. Some sources (for example, online museum databases or photographic archives) may provide blanket permission to reproduce their images for certain types of uses. Check your source for terms and conditions and detailed information on how to credit their images.

Summary:
Create a figure number. Write a caption for the photograph. Include a credit line.
