In Windows 7, I can't get pictures to show as thumbnail previews. I've tried three different methods suggested on this site. Why is this so difficult?__
The three methods I've tried are as follows:
1. Open the folder in Windows Explorer and click the down arrow next to Views at the top. Choose Medium icons and see if the thumbnails start working again.
2. If not, click on Organize, then Folder and Search Options. Click the View tab. Make sure that "Always show icons, never thumbnails" does not have a check mark next to it.
3. Open Control Panel. (Classic View). Click on the System icon. Click on the advanced system settings link. Under Performance, click on the Settings button. In the Visual Effects tab, Check "Show thumbnails instead of icons.”
