Here's a list of places to find high quality, public domain images of historical costume, settings and objects. I'm mostly interested in 1750 to 1830, so these will be best represented
[ETA -- now has both links and the URL printed out.]

There are over 200,000 of them. Just wonderful.
Web Gallery of Art (Again, these images are public domain)
I had just a terrible time finding the 'search' feature. Go to Gallery and the search tab is at the bottom of the page. Not a bad search engine once you find it.
http://allart.biz/
Art.com This is a commercial site, beautifully searchable by subject. Many are Public Domain, but a good many are copyright, so you have to use common sense. If possible, search here to find the works, then find the image at a site with better resolution.
