How do I send a variable between one movie to another?

I’m trying to work on a friends site. He wanted a bios page to show some pictures. I have structured it so that when you click to see the bios section, it loads the bios flash movie. I also have a separate flash movie for the gallery. I wanted it so that, if you are in the bios and click on a picture, it will take u to the gallery section, and bring up the picture that you selected.

Is this even possible? Any assistance on this would be very helpfull. Thanks.
