If you use an image that you don't create, it should have a credit line at the end of the caption. APA states that the image should be in your list of references as well. If the reproduction of a copyrighted image is not fair use, you would need to obtain permission from the copyright holder to use it. The reprinted with permission statement is not needed when it is fair use.
