Thumbnails not shown in Edit screen

[kittyw2]

When I go to "edit this gallery" after uploading my pics, the thumbnails are not displayed in the column folowing "title." Under the thumbnail heading it says 'not shown."What do I have to do to get them back? They were working last time I uploaded pics to the site!

Not sure what is going wrong here, but your thumbnails does display properly in the gallery. So is this a big concern? Maybe it is a passing thing.
