Answer 1

yeah, I'm pretty sure that doesn't work, you just a sort of "invalid content" or similar error; Unless there has been an update to graph API is it NOT possible to add photo tags via the API. The only thing you can do is upload the image, add a "tag" button and redirect the user to the image on Facebook where they can tag it manually, such as here: http://o2-academy.vccphub.com/snapbooth.php/snapbooth/image/2012-01-21-032244-o2ac1-1740164044-8972579
