View Photoshop psd files in Explorer

Ever since Photoshop 7 you could no longer view psd file thumbnails in Windows Explorer. To view thumbnail images for Photoshop PSD files in Windows XP and Vista go to http://www.josh.biz/tech/6-view_psd_thumbnails.html
where you will find instructions and a downloadable zip file. The instructions are on this web and in a txt file included in the ZIP. The last step in the instructions is double click Adobe.reg to run this program. After running this Vista users should Restart. Also it won't display a thumbnail if the file is a layered file and the top layer's visibility is turned off.
