Although Credo and Britannica are not devoted just to visual resources, they both often have accompanying images with their articles. Britannica even has links to videos and other helpful outside sources!
Resources listsed are both library databses and outside resources. The outside resources include the Library of Congress and New York Public Library online digital collections. These resources may have images of people living in your particular time period/location.
