Answer 1

If you post a photo successfully, the Graph API will include an Object ID in the response, like

{ id: 1234567 }

Now, you can query the likes via

GET /1234567/likes

Then, you have to count the likes by iterating over the result array, or use an FQL query instead:

GET /fql?q=SELECT+object_id,like_info.like_count+FROM+photo+WHERE+object_id=12345667

There, you'll have the like_count directly.
