There's a post in the dpreview forums linking to a web page http://www.idfoxx.com/forum/viewtopic.php?p=18662&sid=6bbf1ecbb3a940a790f1363fecfe0730
announcing a Windows Shell Extension that lets the standard Windows file browser know how to extract thumbnails from .PEFs (and from a plethora of other file types, including DNGs). If you would like to see thumbnails from your Pentax RAW files it might be worth giving this a try. I haven't tried it myself yet, but there are several favourable reviews in the discussion thread at the above link. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
