Caching

I have a .fla which loads a picture externally using loadClip. This picture is continually being updated. Is there any way to force the player to download this picture each time the movie is started. I do not want the player to use a cached version of the picture.

I believe you could pass useless information to the URL, but I dont know if that would work for an image. For example, loading a .swf without using cache would be [AS]loadMovieClip(“http://www.sitename.com/main.swf?rnd=”+Math.round(Math.random()*100));[/AS]
