The common problem of a RAW photo is that you must open it with the apropriate tool on your PC in order to preview it. Yesterday i came across with the dpmagic [url]http://www.dpmagic.com[/url] (following a post from dpgr.gr), a nice tool to produce thumbnails directly from raw and of course it supports my favorite Olympus 5060 :).
Installation is easy and working with that is easier: Open a folder that has raw photos inside. Switch to thumbnail view and here is the preview of your photo.
Very,very nice work. And it is free
