I'm trialing Courier at the moment and there appears to be some variation in how media items are treated. If I add a new media item and reference it using a media picker then the media item is copied across to the destination media folder and the new entry appears in the destination media tree. If, however, I add a new media item and add it as an image in a rich text editor then Courier still copies across the physical image to the media folder but it is not added to the destination media tree. A quick check of the umbraco database confirmed that it had not been added and additional logging added to see if the Extracting event was fired on the MediaItemProvider shows that the media datatype item had not been moved accross, just the physical folder and file.

The page still works as the media item is in a folder with the correct id. Is there  a reason for this behaviour and is it a limitation of courier when newly added media items are only referenced in rich text editors?
