i also have a similar problem where i moved the photos from one folder to another and now i have the pics showing and black boxes with white x's in like a unloaded thumbnail of the pic. its like the cache still has thumbnails in of where the pics used to be. tried rebooting. tried deleting them on phone but nothing. pc suite and storage mode wont help coz duplicates dont exist.

any idea on how to refresh the pic library or thumbnail cache?
