Well this is just a little registry hack that changes the size of the thumbnails of images that are displayed in windows explorer by default. The default size is relatively small and most people surely would like a bigger size for the thumbnails to get a better preview of the images. To do that you have to add a new entry called ThumbnailSize to the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer
Select Edit – New – Dword Value and name it ThumbnailSize. Double-click the new entry and select decimal and a number between 32 and 256. The default value for the thumbnail size is 100, if you would like a bigger size increase the number above 100, if you like smaller ones choose one below 100.
The new settings will become active after you restart your system.

cheers,
Nuthing like reghacking by hand =D
I prefer to do that by hand, it’s better so you understand what you are doing, where you are doing it and how to reverse it if something unforeseen happens.
Hmm, doesn’t seem to work for me. I tried 255 restarted my system but no difference… And by the way, how big will the images be with 255?
EDIT: Nvm, I managed to miss the b button so it said ThumnailSize. Shall test again.
