flash actionscript 2.0 (importing a file from outside the flash file)

Question

I am using flash actionscript 2.0

My boss just asked me to design a website. But the customer can upload his own jpeg and swf files.

He told me to find a way so they can upload the files from a file outside the flash file. I've been reading some stuff but i guess its called calling an action or importing a file from outside?

Thank you for your time :):) It would be a huge help cause it due today :P
