GET POST twitter profile picture

Hi guys, I made a bot for twitter to create accounts, and I wanna integrate also the update profile picture feauture.

I never used GET POST methods before, NEVER, so I am kind of new to this things.

Can somebody suggest how to get it done ?

I installed httpfox to monitor the traffic when I upload a picture, but seems too advanced for what I know ATM.

Any suggestions ?

Thanks in advance

If I was doing this I'd use firebug to figure out the URL that needs to be posted to, then use curl to mimic the post.
Can't speak for httpfox as I've never used it - so hope firebug will be easier to find your way around.
