see this http://www.yobt.tv 
look at a video and watch how it creates a thumb nail pic of each part of the movie
then as the movie plays you can see the thumb nail move as the video plays
you can select the thumb nail pic to go to that part
the thumb nail pic and the FLV viewer are separate i think,
what tool is used to convert this?

another question
i want to pass out a link with some movies on it
but i want the link to expire at a certain date
i need some kind of link generator and i dont want to keep having to manually do it at my website by changing it or deleting it
