php - Share a picture on facebook, not via URL -

-

i have website , share pictures facebook using button.

i confused how share of picture works, have implemented share of picture via url http://m.facebook.com/sharer.php?u=[url]&title=[title] , requires picture hosted on server. wondering other options available?

is possible share picture directly on facebook (like if user uploading on facebook itself)? have heard oauth don't understand if using 3rd party libraries or if part of facebook libraries?

many thanks

you need use /me/photos endpoint upload picture, there example code in docs: https://developers.facebook.com/docs/graph-api/reference/user/photos/

the user must authorized publish_actions in order make work.

here´s more information authorization/login:
