*
* If a photo was uploaded into the message using the ajax uploader,
* it can be seen by anybody. Set the permissions to match the message.
* Ideally this should be done when the photo was uploaded, but the permissions
* may not have been set at that time, and passing the permission arrays via
* javascript to the ajax upload is going to be a challenge.
* This is a compromise. Granted there is a window of time when the photo
* is public. You are welcome to suggest other ways to fix this.
* When a photo was uploaded into the message using the (profile wall) ajax
* uploader, The permissions are initially set to disallow anybody but the
* owner from seeing it. This is because the permissions may not yet have been
* set for the post. If it's private, the photo permissions should be set
* appropriately. But we didn't know the final permissions on the post until
* now. So now we'll look for links of uploaded messages that are in the
* post and set them to the same permissions as the post itself.
