Bonsoir Wolfgang !

I tried according to your method (without arrangement and extra run) without result, I tried others possibilities without result. The index page is never ok with \setuparranging... Surely I did not understand.

I wanted to make a booklet of musical scores in A5 (24 pages), just with successive png and index for each score : ------------------------

\starttext
\externalfigure[Alaude][width=\textwidth]\index{Alaude}
\blank
\externalfigure[Amazing][width=\textwidth]\index{Amazing}
....
\externalfigure[Valse_5T][width=\textwidth]\index{Valse a 5 temps}
\blank
\externalfigure[Valse8Temps][width=\textwidth]\index{Valse à 8 temps}
....
\externalfigure[ValseEcossaise][width=\textwidth]\index{Valse écossaise}
\page
\setupregister[index]
   [n=2,pagestyle=bold]
\completeindex
\stoptext

--------------------- Never mind ! I will do it in A4.

Thank you for your attention !

Try to produce a document without arrangement and make an extra
run afterwards where you arrange the pages. You can use modes for this.

\startnotmode[arrange]
\setuppapersize[A5][A5]
\stopnotmode

\startmode[arrange]
\setuppapersize[A5][A4,landscape]
\setuparranging[2UP]
\stopmode


Process your document first with

    context my_document.tex

and make an extra run at the end with

    context --once --mode=arrange my_document.tex
