In text, the standard in-text citation would go as a caption below the image: Figure 1. Title (Author, Year)
In the Reference List you will list the full reference to the book/book chapter/journal article as normal.
If the image can be accessed separately, cite as an independent source. Otherwise, cite the source of the image (i.e., the web page on which the image appears).
Examples are shown in the APA Guide.
