I am curious how a particular site works. Its main page is
http://site.com/page.php
when i visit a page its
http://site.com/page.php?id=123456

Then, when i download a file or image its
http://site.com/dl.php?id=123456&start=1

I looked at the html of the page and the images seem to be in sub directories. But the image that the id point to isnt. I tried getting the header (no need to login which is nice. I did this while killing time before my other question was answered) and i recieved the below. How is the image or file being stored and is there a way i can resolve its location? (school isnt in, so it cant be homework ;))

I am hoping the files arent stored in a DB. Somehow i dont think it is, but it could be possible. I thought the header would redirect me to the file but it didnt.
