394061 Upload photos to facebook

Hi Guys, I am looking for a simple script, preferably javascript that I can then incorporate into other scripts I am running that will upload an image to a specified users account. I.e. the user will input their login id and the script will then automatically upload a specified photo to an album on the users facebook site. The main thing here is that users will not be wanting to input there password so you need to know wether it is possible to upload to the users account without that? If this is possible, we can move on from there.
