The preview handler finally registers. For now it registers for Nef, Pef, Cr2 and Dng.

I present to You, the first alpha release of RawPreview. For now it's only a preview handler for Windows Vista allowing preview of different raw image formats in the preview pane. I'm using dcraw to extract the embedded thumbnail. It currently only registers for *.pef, *.dng, *.nef.

For the future:

• Support thumbnail creation on Vista and XP
• Be able to edit the file-types it's registered for in some kind of GUI
• Show exif information in the preview on Vista
