Saving preferences ? (or something like that)

hi, im new on this board (btw. Great site!) Well, i have a question about flash, and wonder if it even is possible to solve. I want to be able to save the preferneces in a flashmovie. i.e. im gonna make a movie (to put on a website), and the user sould be able to change a picture within the flashmovie, and when the page is reloaded the movie sould be what the user selected.
gosh, it’s really hard to explain stuff like this (even harder when i can’t spell English properly :))
