Our app shows some Facebook posts from artists that our users follows. We want to enable our users to share posts they like back to their timeline (like the share button you see under each post in the Facebook Feed).
We tried to do this using the Facebook web dialogs, but we keep running into errors. For example: When trying to share a post of type photo: If we set a parameter "picture" with the picture url, we get an error that the feed dialog should not use a picture coming form the FBCDN.
We can share the photo as a link, but than the photo itself doesn't appear on the user timeline.
Is there a way to mimic the functionality of the built in share button?
