Is there a good website for public domain images?

Can I use the art images from the Art Renewal Center website (www.artrenewal.org) for commercial projects?

• The Art Renewal Center website has many high resolution images of old paintings. I would like to use some of these to produce a calendar and other items which I would sell. My understanding is that if the original artist has been dead for 70 years or more, the images are in the public domain. Is this correct? As long as I avoid using artwork from more recently deceased or living artists, would I be "legal"? I've searched the website but I can't find any specific references to copyright of the artwork or any mention of public domain issues. It's almost as if they are avoiding the issue, but I may just have been looking in the wrong places. Any advice would be useful, as would any suggestions where I can find high resolution art work in the public domain.

  You're right on the public domain thing I'd check out the Smithsonian and Louvre sites for more pics.
