Am endeavouring to explore Wolfgang's very 'elegant' solution to this
facing page challenge. The exploration has included a look at
base/mkxl/page-inj.mklx (thanks Sreeram for reminding me of this) where
I see immediately that the approach is experimental and where it says
also that 'probably more alternatives will be added'. I wonder if that
last phrase also includes the ability to manipulate the image(s) either
generally or in individual cases?
So, for example., say I need (and in fact I do!) to change some aspect
of individual images, e.g. I might want to scale=500, or fiddle with
width/height of a particular image. At the moment I cannot see a way of
doing this for each image. I wondered if the commented out setups in the
response to this question might be a clue, but so far haven't been able
to get that to have any effect.

Appreciate your assistance. I'll do my best with what you offer here.
Of course, I've always said these images are at the beginning, not
"the end of their respective chapters" and I've already indicated how
the images are named, simply as Chapter1.jpg and so on, so I'll need
to work around these differences in your example. But with trial and
error, let's hope I get there!
The example below uses a different mechanism to add images at the
start of a chapter. In the example you have to pass the name of image
as userdata argument of \startchapter but in the commented \setuphead
setting you can see how this can be automated.
%%%% begin example
% \definepageinjectionalternative
% [chapter:image]
% [renderingsetup=pageinjection:chapter:image]
%
% \startsetups [pageinjection:chapter:image]
% \clip
% [width=\framedwidth,height=\framedheight]
% {\centerbox{\externalfigure[\dummyparameter{name}][factor=min]}}
% \stopsetups
\definepageinjection
[chapter:start]
[empty]
[page=left]
\definepageinjection
[chapter:insert]
[previouspage]
[%alternative=chapter:image,
pagestate=stop]
\setuphead
[chapter]
[beforesection={\pageinjection[chapter:start]},
insidesection={\pageinjection[chapter:insert][name=\structureuservariable{image}]}]
% \setuphead
% [chapter]
% [beforesection={\pageinjection[chapter:start]},
%
insidesection={\pageinjection[chapter:insert][name={chapter\namedheadnumber{chapter}}]}]
\setuppagenumbering
[alternative=doublesided]
\setupexternalfigures
[location=default]
\starttext
\startchapter [title={Mill}] [image=mill]
\dorecurse{7}{\samplefile{lorem}}
\stopchapter
\startchapter [title={Mill}] [image=mill]
\dorecurse{11}{\samplefile{lorem}}
\stopchapter
\startchapter [title={Mill}] [image=mill]
\dorecurse{7}{\samplefile{lorem}}
\stopchapter
\stoptext
%%%% end example
