hi,

i am looking for some advice please. i want to make a flash site that will have 3 or 4 sfw files. each swf has the same background image that takes up all the movie.

it doesn’t seem right to load it each time i load a new swf on a different level but i can’t see how you set the bg to be transparent. ideally i think i should have a swf with the bg image on it and then that loads the content swf on top. then i could load and unload swfs.

what am i missing??

cheers
