Android code instructions on uploading picture [View all]

I really just need a tiny bit more help with my Android app and might be able to proceed from there...

These instructions are driving me a little crazy. I like this site linked below, but it's sort of ridiculous how they provide the minimum information on every question, basically once they answer and gets their points, they disappear. No conversation is even allowed on that site.

Anyway, this post has instructions on uploading a picture http://stackoverflow.com/questions/2935946/sending-images-using-http-post . I inserted all this code into my app, but it's odd how they don't mention 1) where you actually type in the destination server, or 2) how you properly authenticate to the server, or 3) how the picture is attached during this process (but maybe it's already in the code, not sure).

They are like "bla here's some code". Anyway, I'm just joking around, sorry for the attitude.

Any help with indicating a destination server would sure be appreciated.
