The thumbnail view in windows explorer gives you easy access to a portfolio of images, but the default image size may not be to your liking. To control the thumbnail dimensions, go to HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer. Make a new DWORD value named ThumbnailSize. Double click the value and type in a number in decimal anywhere from 32 to 256. Making it smaller will display many more images on the screen for quicker perusual. Its an immediate change by the way, so keep regedit open and mess around...
Happy Tweakin..
