The Chris Walter photo archive at Photofeatures is steadily being added to, with both images that have not been scanned before and also the newest edits. The most recent of these can now be viewed as a Feed. This page is a JS feed, but it is also available as RSS and ATOM to be added to your RSS desktop reader or browser page (Yahoo, Google home pages etc).
This JavaScript page has just the 30 most recently added images but the feed should have up to 100 images if your reader permits.
