After downloading the Flash ActiveX Control, you can then continue downloading videos using Chrome, and the thumbnail images will now appear in your RealPlayer Library.
If you are not able to view thumbnails in the folder on your PC where the files are saved, this is not a RealPlayer issue; however, this problem may be resolved by installing the Klite codec pack (click here to install) and then following these instructions:
XP users: 1. Open the folder that contains the videos. 2. Click View in the menu. 3. Choose Thumbnails. Vista, Windows 7 & Windows 8 users: 1. Open the folder that contains the videos. 2. Click on the drop-down icon (see the example in the circle below).
3. Choose either Small Icons or Large Icons to display the thumbnails.
Note: If they are set to List or Detail, videos would never show thumbnails.
