We've installed both addons "What's New" and the "New Gallery" (which BTW is terribly slow - any hints on this?)

Now the "What's New" addon also shows the generated Thumbnails of the New Gallery addon without a clickable Filename.

This can be avoided by appending this statement to the Row Filter:

AND (NOT OriginalFileName LIKE '%-True' AND (NOT OriginalFileName LIKE '%-False'))
