Mark Harden's "Artchive" contains images of many essential works of art covered in any survey course. You won't find many obscure artists or rare works here, but if you need a high-quality reproduction of one of the essentials this is an excellent resource. The site is easy to navigate by the alphabetical listing of all the artists and periods/styles on the left of the screen. Each entry has some text and a list of images towards the bottom.

Art Images

Art Images for College Teaching was a personal, non-profit resource created by Allan T. Kohl, visual resources curator at the Minneapolis College of Art and Design-- all photographs were taken by Allan. Most of the images have references to pages of major art history textbooks where the work is mentioned. The images are still available and downloadable, but the site is no longer maintained, and there is no longer any information about image use and permissions.
Selected galleries:
- Colonial & 19th Century America

Flickr Groups

Flickr Groups are themed image collections created by members of the Flickr photograph-sharing community. There are thousands of Flickr Groups, and more are created daily. The size and quality of images within the groups varies, but overall I am impressed with the images I find there. Copyright protection varies by photographer. A very popular protection on the site is the Creative Commons license, which allows anyone to use, distribute, and change the photograph as long as attribution is given to the creator. To the right of each photograph the copyright information is displayed.

- American's Favorite Architecture
- Colonial Churches of New England
