For the high tech taxidermist out there who keep their reference pictures in digital format, a buddy at work turned me onto this tool http://www.faststone.org/FSCapturerDownload.htm. It's oh so nice for browsing large collections of reference. I'd been using Infranview for sometime now and really liked it but this tool is easier to use and the image viewer (aka thumbnail viewer) has so much going for it. Give it a go, you'll really like it. Best of all it's free.
