Make sure to check with your instructor about how they want you to cite images as it may differ from these instructions.
In both forms of Chicago style, images and illustrations are referred to as "figures".
Label all images with figure or fig. followed by Arabic numerals.
Figures should be accompanied by a caption placed near the figure.
Source information about images is usually not included in footnotes or bibliographies. The captions that accompany each individual should be sufficient citation.
In both forms, instead of including note when you refer to a figure, include a parenthetical reference to the figure number at the end of the sentence.
