The following example is based on Wolfgang's solution using injections: I have
modified the setup slightly to hook into \externalfigure's {width, height,
orientation} using user-variables. With this I think you can place any kind of
image (portrait or landscape) correctly by using width, height, and rotation.
I picked up some images of cows, 'spider', 'hacker' and 'mill' and have them
renamed as {chap-cover-1, ... chap-cover-6} for a total of 6 chapter images.

Re: [NTG-context] help with facing page image
If you mean
\setuphead
[chapter]
[beforesection={\pageinjection[chapter:start]},
insidesection={\pageinjection[chapter:insert][name=\structureuservariable{image}][name=\structureuservariable{scale}]}]
\starttext
\startchapter[title={My title}] [image=Chapter1.jpg][scale=500]
\setups[pageinjection:chapter:image]
\dorecurse{7}{\samplefile{lorem}}
\stopchapter
I tried that (and a few other combinations of the kind) but to no effect.

Couldn't you just pass scale as a key-value parameter, similar to how `name` is
passed in Wolfgang's solution?

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.

It came to me while writing the above lines and wanting to report that i see some warnings about fuzzy paragraphs (forget about them). To make it short it triggered a memory about a rather old thread, where Hans mentioned that the exporter is not so fond of and keen about LaTeX style \chapter, \section commands and that he advises to use \startchapter \stopchapter, \startsection \stopsection, etc. pairs instead. So i gave it a try and exchanged all occurrences of \chapter, \section, \subsection, \subsection by their \start* \stop* equivalents and now the xml document and the html document are a lot largen. They now conatin nearly the whole document. There are sill plenty of LaTeX style commands around in the document for which exporter friendly \start* \stop* replacements exist. I will continue this route and 'am comfident that in the end will get get a full xhtml and true e-book for my lecture notes. :-) Thank you very much for triggering memories.
