Solved: Windows 7 image thumbnails have disappeared!

About a week ago thumbnail images suddenly stopped showing (mainly .jpgs & .pngs) in several of my folders. It
seemed to be fairly random across all folders & drives (2 partitions on C drive) whereby some display correctly
within a folder but most now show as windows photo viewer icons.

Images uploaded in "My Pictures Folder" on C drive are not affected.

I have done the obvious:-
1. in folder options > always show icons, never thumbnails (unchecked)
2. deleted & rebuilt the thumbnail cache
3. run malwares scans (system is clean)
4. done restores (Microsoft & Adobe updates)
5. selected medium icons to view . . .

Also, using the Windows Photo Viewer default — preview pane no longer works — if Id/click on an image it opens
in a new window.

I had been using Mystic Thumbs successfully for a while to enable me to see .svg, .pspimages & .psd files (as a
graphic designer I want quick access to these) Uninstalling it hasn't made any difference.

Any help is much appreciated!
cheers, whizzy

No suggestions?

 

in folder options>view tab,click on the" Reset Folders" button,do they show in "safe mode?

 

Not quite sure what you mean by "safe" mode but when I reset folders I am presented with the "do you want to reset all folders of this type to the default view settings?"

 

Was finally able to resolve the problem by doing a reformat.
