Oh, of course, Philipp Gesang recently reminded me.
I would like to use \startpostponing[right], but fixed pages are ok.


This works:

\starttext

\startpostponing[3]
	\section{Tufte}
	\input tufte
	\strut
	
	\page
	\strut
	
	\page
	
	\section{More Tufte}
	\input tufte
	
	\page
\stoppostponing

\dorecurse{30}{
	\section{Knuth \recurselevel}
	\input knuth
}

\stoptext


But if I try to put graphics in layers within the postponing, I get  
empty pages.
Further, if I put that postponing stuff into a macro (see below), I  
get errors about \par ending the buffer. I guess I’d need some  
unexpanding, but where?
Without \def, I get 2 (instead of 3) empty pages, but with page  
numbers. I need to switch off the pagenumbering for the first two  
pages (because it’s a transparent page that doesn’t count); it’s  
probably also a problem fixed-page postponing...

\def\DoublePicAt#1#2{
	\startpostponing[#2]
	\setuppagenumbering[state=stop]\setuppagenumber[state=stop]
	
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	
	\page %[right] doesn’t work
	\strut
	
	\page
	
	\setuppagenumber[state=start]
	
	\resetlayer[bg]
	\setlayer[bg]{\externalfigure[#1-hg][height=\dimexpr(\paperheight 
+6mm)]}
	\setupbackgrounds[page][background=bg]
	\strut
	
	\page
	\setuppagenumbering[state=start]
	\stoppostponing
}

Thanks in advance!

Greetlings, Hraban
