Hi Guys, There is a lot of out dated information in this string. Here are the facts, as of February 2010.
1. You need to be a Youtube Partner to get access to customizable (upload your own) thumbnails. 2. YouTube used to pull it's thumbnails from preset points in the video timeline. Under this method you could insert a still frame right in the middle of your video to customize the thumbnail. This is no longer in use and will not work. 3. YouTubes new method utilizes an algorithm to determine the frame that is most representative of your video. So if 75% of your video is purple then it will choose a purple thumbnail. There is no way to trick this system so don't waste your time. (this info comes straight from the mouths of the people at YouTube). Hope that helps. -Damien
