Category talk:Video samples of films

Thumbnail issue
When I added this category to File:American Beauty gymnasium.ogv, File:S08-first contact borg queen assembled.ogv, and File:S03-the search for spock enterprise destructs.ogv, the thumbnails of the video samples were displayed on the category page. How can we categorize non-free video samples of films without the thumbnails showing up? Erik (talk) 21:52, 28 January 2010 (UTC)
