Thanks, Shawn, but that proves my point. In the Screenie you sent me, "preview" simply shows a blank Icon of the file and a text description of the file's contents. In XP I would see a photographic miniature of the Web page.
Still, I appreciate all of your help in this matter and the genius of the Internet. You in Texas and me in Sydney, OZ, able to communicate in seconds is still a wonder to me. Give my regards to "George" if you see him !
Thanks again, Shawn.

Shawn,
I've been at cross purposes with you over the preview pane in IE 7. I installed Firefox and it immediately brought up a very large preview of the pages of that Nikon Camera review as soon as I hovered the cursor over the page !
I then went back to IE7 and tried it. No go, but I then remembered the advice re "Organize/Layout/Preview pane". That brought up a black panel on the right and I hadn't realised that it had scroll bars for left/right and up/down. As soon as I did and expanded it, there was the preview of the whole page ! Now we are on the same wavelength and I'm a lot happier. I still don't get thumbs of the whole contents of all the pages but the response to hovering the cursor is immediate.
Winston Churchill said that America and Great Britain are two great Countries seperated by a common language ! I think that's what has happened here. These two
screenies explain it better. The main thing is that I now see what you were trying to get across to me and I hope this may help others with the same problem. It took that Firefox install though for me to realise what I was missing.
Thanks for everything, Shawn. I live in OZ but come from London, hence the Winston reference.
Fred

Thanks for the steps discribed in the captioned, which are very good to follow. Unforunatelly none did help my problem.
I tried them ALL but none did solve the problem. In fact if i open a folder with pictures (.jpeg) the thumbnails are shown quickly but then overwritten by the generic icon.

It might be that i am a bit low on RAM which i plan to increase when i am back in the country in two weeks.

Thanks anyway for your work and maybe my reply helps somehow to uncover other problems.

Thanks to your info, I was able to solve much of my thumbnail problem. I tried all methods, to no avail, until I ran your suggested SFC / SCANNOW. Apparently problems were found. I can now see thumbnails for jpg files that reside on my PC. I do have one remaining problem.
I have the majority of my pics on an HP Media Vault (NAS). I can't see the thumbnails for those pics when I explore to the pic folder on this networked drive. I'm not certain of the operating system on this NAS, but I believe it is a neutered version of Windows Home Server.
Should I be able to see thumbnails on an external drive controlled by Windows Home Server?
Input on this question, and on this problem in particular, would be greatly appreciated.
:D:confused:

Hello John, and welcome to Vista Forums.

Yes, you should see thumbnails of the images in a network folder while viewing from within Vista and you have the icon view set to at least "Medium icons".
