Flash Resource for Flex Code

Hello

I'll start at the end and work back. Bare with me! I want to create a .swf
file, to place in a web page, which will comprise an HSlider and above it an
area to display a short image sequence. As the user drags the HSlider from
left to right the image sequence will display the appropriate frame allowing
the user to effectively scrub the movie.

I have tried many, many times to do this using an FLV file and the Flash
Player web plug-in just doesn't interpret the 'seek()' method properly.

This time I thought I would try a different approach. I want my Flex
developed swf to be generic so that I can pass it a parameter defining the
movie which I want it to play and have it load this movie and allow the user
to interact with it. For the movie I want to somehow import an image
sequence into Flash Professional and save this as a resource which my
generic Slider can load and display.

Would anyone be able to suggest if this is possible and how I might go about
it. Alternatively you may have an alternative suggestion. The main thing is
to have a single UI able to load and display any prepared movie resource.

Thank you.

Chris
