In short adding thumbnail images to the Media Center video library is easy. Simply place a .jpg with the exact same file name as the movie file in the same videos folder. For instance to have the file “Bourne Ultimatum.dvr-ms” show a thumbnail in the videos section of Media Center, put a file named “Bourne Ultimatum.jpg” in the same folder.
The tricky part is getting the file to show up properly, it needs the correct dimensions or the image will be cropped. The dimensions Media Center displays are 320×240 (WxH). To find an image with those dimensions I go to Google Images and search the movie title. Google Images provides the dimensions of each image file. As long as W/H = 1.33 you’re good. So for instance a jpg with 1024×768 dimensions works just as well.
