in short it's not possible to do what i wanted annonymously, moreover at the moment, only some of the API works in the web site by accident only, if u are not logged in FB do not want to let u see any page and anyone, considering the last article about their cooperation with the US gov. it's not surprising.
In any case i just use grease money and FF to get a full page\album and then download the whole thing and i i need scrapping i'll do it on those pages with a script. basically if i log in i can get a full page using the scripts in script monkey.... though script monkey is easier since he has the browser to parse all the data and works inside the browser...
I gave up after 3 weeks...
