Sorry for coming back again and again, but I’m still stuck, and my deadline
is overdue.
* I need full-page pictures on defined pages in the middle of a chapter.
* I don’t care if I must define "on page x" or "on the next right page after
the current paragraph".
- The only way for full-page pictures (i.e. bleeding over the page) that I
know of is layers.
- The only way to interrupt a story with full-page content that I know of is
postponing.
(makeups were a dead end so far - maybe they can help to get to a right page
withput using \page[right])
While each works for itself, I can’t get layers working within postponing.
And when that works, I need to wrap it in a macro, since I alway need to
define and postpone three sequential pages.
Without postponing, this works:

\setuppagenumbering[alternative=doublesided]
\definelayer[bg][x=0mm,y=-3mm,width=\dimexpr(\paperwidth+3mm),height=\dimexpr(\paperheight+6mm)]
%\definemakeup[rightpage][page=right]
\def\DoublePic#1{
       %\startmakeup[rightpage] % error!
       \page[right]
       \resetlayer[bg]
       \setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}
       \setupbackgrounds[page][background=bg]
       \strut
       %\stopmakeup
       % empty back of the first picture, since it’s printed on transparent
paper
       %\startmakeup[rightpage] % error!
       \page[right]
       \resetlayer[bg]
 \setlayer[bg]{\externalfigure[#1-hg][height=\dimexpr(\paperheight+6mm)]}
       \setupbackgrounds[page][background=bg]

This doesn’t:

\setuppagenumbering[alternative=doublesided]
\definelayer[bg][x=0mm,y=-3mm,width=\dimexpr(\paperwidth+3mm),height=\dimexpr(\paperheight+6mm)]
\def\DoublePicAt#1#2{
       \startpostponing[#2]

       \resetlayer[bg]
       \setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}
       \setupbackgrounds[page][background=bg]
       \strut
       \page[right]
       \setuppagenumber[state=start]
       \resetlayer[bg]

Can you show me a way to use layers within postponing, please?
A first step --- still quite similar to your macro. Hope it helps just for now.
\setuppagenumbering[alternative=doublesided]
\definelayer[bg][x=0mm,y=-3mm,width=\dimexpr(\paperwidth+3mm),height=\dimexpr(\paperheight+6mm)]

\def\DoublePicAt#1#2{
       %\startpostponing[#2]
       \page[right] % tried also makeups...
       \resetlayer[bg]
       \setlayer[bg]{\externalfigure[#1][height=\dimexpr(\paperheight+6mm)]}
       \setupbackgrounds[page][background=bg]
       \strut

       \page[right]
       \setuppagenumber[state=start]

       \resetlayer[bg]
       \setlayer[bg]{\externalfigure[#1-back][height=\dimexpr(\paperheight+6mm)]}

       \setupbackgrounds[page][background=bg]
       \strut
       \page
       %\stoppostponing
