Found this somewhere?. To Enable thumbnails: All Windows versions since 98 can show common graphics file types--.bmp, .gif, .jpg, and (in later versions of Windows) .tif--as thumbnails. Choose View, Thumbnails from a folder's main menu bar or from its right-click menu. In Windows 98 you won't see this menu option, but just press Backspace to move up a folder level, right-click the folder that contains the images you want to see as thumbnails, and choose Properties. In the General tab of the Properties dialog box, check Enable thumbnail view and click OK (see FIGURE 2). The next time you open this folder, you should see a Thumbnails option on your View menu.
