I am successfully posting an image to user's feed with "me/photos" from my iOS app I develop. It appears on the feed, and also the text below that:
Like · Comment · Share · 7 minutes ago via [APP NAME] ·
The [APP NAME] is a link, and it correctly takes to the app's Facebook page. Everything is fine.
However there is a small icon just before "Like", and it seems to be a default picture icon, and not the icon of my app. (Note however that it has a link, and correctly takes to app page).
How do I change it to become the app's icon?
