Resolving window 7 should not display thumbnails

By default, the Windows 7 system automatically displays the image file icon as a thumbnail, and once we find that the icon for the image file is uniformly displayed as green hills and white clouds, the image file thumbnail function of the corresponding system is accidentally closed. To get the thumbnail functionality back to normal, we can set up the Windows 7 system in the following ways:

First, open the Windows 7 system's Start menu, select All Programs/attachments/Windows Explorer commands from the, in the Pop-up System Explorer window, click Organize in the menu bar, and select folder and search options from the Drop-down menu. Open the Folder Option Settings window for the corresponding system;

Second, click the View tab in the Settings window, pop up the label Settings page shown in Figure 1, check that the "Always show icon, never show thumbnails" option is selected, and generally, when we encounter a symptom that the thumbnail cannot display, this option is often selected. At this point we have to cancel the selected state of the option, and then click OK to save the above set operation, so that the thumbnail can be normal display.
