Not able to see all images or HTML documents

The steps below require you to enter the computer registry. Before following these steps, we highly recommend you learn more about the registry and its precautions to prevent additional issues with your computer. Additional information about the registry is available on our registry page.

To resolve this issue, click Start, select Run, and type the command below.

Regedit <press Enter> (for Windows 98 and ME users).
regedt32 <press Enter> (for Windows 2000 users).

Once in the registry verify following keys exist.

HKEY_CLASSES_ROOT\<file type>\ShellEx\

Within each of these keys, verify the following value exists.

(default)  =  "{7376D660-C583-11d0-A3A5-00C04FD706EC}"

If this value does not exist, create it by following the steps below.

  1. In the key that the registry value does not exist, click Edit, New, then String value.
  2. For New Value #1, type (default)
  3. For the data, copy the below bold text and paste it into your registry.

Unable to see animated GIF's

Animated GIF images only display the first frame of the picture and will not be animated.

Unable to see some JPEG files

A JPEG (.JPG or .JPEG) can be created in four-channel, CMYK color format. Windows is only able to display .JPG files that are in three-channel RGB.

If you cannot see any .JPG images, the extension may be corrupt and may need to be added into the registry. Windows 2000 users can add the below registry value, if it does not already exist.

Open the registry by running the Regedit command and move to the below registry directory.

HKEY_CLASSES_ROOT\.jpg\ShellEx\

Next, move into the below directory if it exists. If this directory does not exist, create a folder with the below name.

{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}

Once in the above directory, click Edit, New, then String Value. Double click the new string and enter the below value.

{7376D660-C583-11d0-A3A5-00C04FD706EC}

Finally, highlight the string. Click Edit and select Rename, then rename the string to "(Default)."
