Loading a random background image with a preloader

hello

I’ve been following the Loading a Random Image tutorial from kirupa but I can’t seem to make my image*.swf’s to work…in it all I have is 3 frames, where the first 2 frames are for the preloader and the 3rd one is for the image… but all I get is the loadBar fully loaded (but with no animation, just static) and no image… does that code from the kirupa tutorial stop the *.swf to make anykind of anymation?

another question is about how to simple load a movie on enter frame with a movieclip defining the location where it should be loaded to… shouldn’t it be: location.loadMovie(“movie.swf”) ? simply… no?

thanks in advance…
