When most people link to YouTube videos, it ends up embedding a still image of the first frame of the video. You can then click on it to start playing.
I linked to my demo video in my demo competition entry post, but I couldn’t figure out how to do the same thing. I personally prefer not to force someone to start downloading a video if they didn’t want it. Is there a simple way to do this? (Apart from having to manually save the first frame out as a jpeg).
