Go to Folder Options in the Control Panel and select the View tab. The first entry allows you to select either the generic pic or the thumbnail for each picture. Un-check the box and you should be good to go.
Neither old .jpg images nor newly created .jpg files can be seen in windows 7 file explorer preview pane. The same generic sample placeholder image(picture of water with a mountain in background) appears for all image files. (not sure about gif, etc.) Changing "view" does not make a difference. Files open correctly. I'm wondering if this is just a setup issue. It would also be nice to see my Snips with other Pictures, by default. I rarely had trouble navigating XP, but have a feeling I have much to learn about 7. Maybe I should jump to 8?
