I can no longer see thumbnail images for .jpg, .gif, etc. image files as i used to. The problems started after installing Microsoft Office 2003 (i already uninstalled and reinstalled it and it did not fix the problem). I had found this help topic:
----------------------
SYMPTOMS
When you open a folder that is configured to show a thumbnail view of .jpg files, you may see an outline of the thumbnail and a small program icon where the image should be displayed.
CAUSE
This behavior can occur if the file association for the type of file you are trying to preview has been changed by a third-party program.
RESOLUTION
Click Start, click Run, type regedit in the Open box, and then click OK.
Open the HKEY_CLASSES_ROOT\.jpg registry key.
Create a new registry key and name it ShellEx.
In the ShellEx registry key create a new key and name it:
{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}
In the {BB2E617C-0920-11d1-9A0B-00C04FC2D6C1} registry key, edit the default value to use the following value data:
{7376D660-C583-11d0-A3A5-00C04FD706EC}
Of course, this example fixes only the .jpg file type. You need to repeat the procedure for the .gif key and any other key that refuses to show a preview. The method outlined above won't work for every file type, but you should be able to preview images having any of the following extensions: .art, .bmp, .dib, .gif, .jfif, .jpe, .jpeg, .jpg, .png, and .wmf. Have fun!

However, when i go to create the shellex key, i get an error that the registry cannot be edited. Any ideas?
Thanks!
