Thumbnail view of jpg files

[Feesh]

I'm running windows 2000 and only get an icon (no
picture) when I enable thumbnail views of jpg files. If I
change the extension to JPEG I see the thumbnail picture.

Any suggestions? I don't want to change all my pictures
to JPEG....

Check in the registry to see if any of these keys or data are missing:

HKEY_CLASSES_ROOT\.jpg
Name: (default)
Type: REG_SZ
Value: jpegfile
Name: Content Type
Type: REG_SZ
Value: jpegfile

HKEY_CLASSES_ROOT\.jpg\PersistentHandler
Name: (Default)
Type: REG_SZ
Value: {098f2470-bae0-11cd-b579-08002b30bfeb}

HKEY_CLASSES_ROOT\.jpg\ShellEx
Name: (Default)
Type: REG_SZ
Value: (Value Not set)

HKEY_CLASSES_ROOT\.jpg\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}
Name (Default)
Type: REG_SZ
Value: {7376D660-C583-11d0-A3A5-00C04FD706EC}

These can be changed when you install software which takes on this file type to be the application which opens files of that type. Watch out for this behavior.

The preview occurs from the last one above. That is probably the one missing.
