[NTG-context] blank overlay

I need a graphic (a thumbnail) on the right hand pages but not on the left hand pages. Following the instructions in the Metafun Manual page 168 I have assigned different pairs to the two overlays: \startuseMPgraphic{right page} ... \stopuseMPgraphic and \startuseMPgraphic{left page} \stopuseMPgraphic In the left hand area I want to just create a minimal structure that replaces the right hand graphic overlay. What is the minimal code I can use between the start and stop statements? -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html
