Accessing Camera Roll from Browser in iOS

Question

I am working on an in-browser web application which needs to upload a user's photo from the camera roll but i can't seem to figure it out.

I have researched this subject and all the answers i am finding state that you can't access the camera roll directly from the browser. I thought this might be true but then i navigated to the Facebook site from Safari on my iPad and realized that i was able to access my camera roll to upload a picture. If the answers I'm finding are true, how is it that the Facebook's in-browser web app accesses my camera roll?

Thanks for the help.
