This is a problem I've thought a lot about and written many programs to do on a site-by-site basis. Although I haven't really come up with a good solution (and there probably isn't any), I currently scrape websites looking for images. Depending on how you look at it, this can be a considerably harder or easier thing. Basically, to decide which image on a given page is the "most interesting", I look at the filename (and host --- to see if they match), size (filtering out common ad sizes), and placement on the page (in my experience, on a page that has only one "useful" image, it's like to be at the end --- since all the ads are up front).
