What program can I use to scan my HD for HTML templates I have and create a centralized thumbail catalog?

Anyone know of a program that will catalog all of your html pages on your hard drive as images? I have over 900 templates of which some come with images in a .psd,.jpg, ,gif,.png, etc file format that allow programs like Piccasa from Google and others to use those images to catalog my images but I’m looking for a prgram that will scan my hard drive and basically take a screen capture of the index pages so I can see the template look and feel without having to open every index file and using something like SnagIT to compose a screen capture? While I’m at, is there one for Flash that’ll do tthe same thing? Any advice from experience?

Thanks,
Brad
