Sorry, I've misread the question...

Have you tried 
 \placefigure{none}
?

Many thanks to everyone for advice - I combined various suggestions and managed to end up with a landscape picture occupying the full page.
 
The various options for removing the running headline seemed not to work - I was hopeful that headerstate=empty might, but \placefigure seems not to admit this as an option, and I didn't want to get too involved with Hraban's elegant solution for bleeding illustrations (which may well be useful in future work).  At any rate, I cheated by putting this hamfisted code in front of the caption:
 
\llap{\color[white]{\smash{\vrule height 310pt depth 24pt width 24pt}}\kern 12pt}
 
That doesn't remove the headline but it obliterates it!
Best wishes

You already got a few suggestions but for a better answer it is always
helpful to provide a minimal example which shows what you have tried so
far. To create an example without the need for external ressources you
can either use one of the included sample images

%%%% begin example
\setupexternalfigures[location=default]

\starttext

\startcombination[2*2]
   {\externalfigure[spider.eps][combination]}{spider.eps}
   {\externalfigure  [mill.png][combination]}{mill.png}
   {\externalfigure   [cow.pdf][combination]}{cow.pdf}
   {\externalfigure[hacker.jpg][combination]}{hacker.png}
\stopcombination

\stoptext
%%%% end example

or use the dummy library to add random backgrounds to images.

%%%% begin example
\useMPlibrary[dum]

\starttext

\startcombination[3*1]
   {\externalfigure [wide][width=6cm,height=4cm]}{}
   {\externalfigure[equal][width=4cm,height=4cm]}{}
   {\externalfigure [tall][width=4cm,height=6cm]}{}
\stopcombination

\stoptext
%%%% end example
