JPEG Thumbnails Not Working

Here is my issue:
My JPEG photo files in thumbnail will no longer show as a small photo, but only show as a microsoft photo graphic.

I have used the instructions listed at the http://support.microsoft.com/default...roduct=win2000 bit, to repair a problem I had with JPGs not showing, but now the JPEGs will not show. The question is, do I use the same entries in the Reg to make the same repair, but this time under JPEG?

I had posted the same issue in the past with JPG thumbnails, and tried again by adding to that old posting for an answer to no avail, so I am starting a new thread in hopes. I was watching for help since Sept 8th, and I think nobody paid attention to the posting as it looks old. Trying to not break any rules here.

Plodr helped me to resolve last time around, so hoping he sees this posting. That guy is a miracle worker to be sure.
For info, my last thread that talked to the same type of issue is at http://forums.majorgeeks.com/showthread.php?t=262174

I have Win 2000 SP4 as my OS.
