* adds a resource to the gallery when the resource is already stored on disk, instead of

*
* @param ownerId
* @param albumId
* @param description
* @param fullFilePath The real path where the file is stored. This is expected to be
* its final and permanent destination
* @return It will return one of the following constants:
* - GALLERY_ERROR_RESOURCE_TOO_BIG
* - GALLERY_ERROR_RESOURCE_FORBIDDEN_EXTENSION
* - GALLERY_ERROR_QUOTA_EXCEEDED
* - GALLERY_ERROR_ADDING_RESOURCE
* - GALLERY_ERROR_UPLOADS_NOT_ENABLED
* or the identifier of the resource that was just added if the operation succeeded.
