Post photo to facebook fanpage.

Hi. I want to send a photo from my mobile app from Camera or Gallery to my Facebook fanpage. I can send it to my own feed using [login to view URL]('me/photos', data , "POST", function(e){ //some stuff..... But i want this [login to view URL]('pageID/photos', data , "POST", function(e){//some stuff...... I think the key to the operation is to get the page access_token but i havent got a clue how to get it. This is a small job if you know what you're doing. Thats why i only will pay 30$ for it. I need this for Titanium. PM me for more code and details.
