A lot of people ask me where they can get good-quality images, so I thought it would be good to have one post that I could bookmark and send out to people. I mentioned before that I use iStockphoto.com the most (as well as more expensive sites — though I do that much less now — and high-quality photo discs from Japan). A few people gave links to their favorite free or inexpensive sites as well. Below, then, are links to both inexpensive sites and sites offering free images in searchable databases (but check terms of use). The quality ranges from "excellent" to "not too bad."

GRIN
GRIN is a collection of over a thousand images of significant historical interest scanned at high-resolution in several sizes. This collection is intended for the media, publishers, and the general public looking for high-quality photographs. Please note that downloading these image files may take some time, although searching and browsing should be relatively quick.
