You could write your own macros and comapre the width/height ration of the
picture with the reation of the box, is simple example is shown below.
\starttext
\start
\setbox\scratchbox\vbox{\externalfigure[mill]}
\dimen0=\wd\scratchbox
\dimen2=\ht\scratchbox
\framed[frame=on,strut=no,width=8cm,height=2cm]
{\dimen1=\hsize \divide\dimen1 by \dimen0
\dimen3=\vsize \divide\dimen3 by \dimen2
\ifdim\dimen1>\dimen3
\externalfigure[mill][height=\vsize]
\else
\externalfigure[mill][width=\hsize]
\fi}
\framed[frame=on,strut=no,width=2cm,height=8cm]
{\dimen1=\hsize \divide\dimen1 by \dimen0
\dimen3=\vsize \divide\dimen3 by \dimen2
\ifdim\dimen1>\dimen3
\externalfigure[mill][height=\vsize]
\else
\externalfigure[mill][width=\hsize]
\fi}
\stop
\stoptext
