the grid options as discussed with sections, are the ones that are taken care of by the \snaptogrid macro; the grid key in externalfigure is not related to that, it relates to scaling, as in

\setuplayout[grid=yes] \showgrid \setupcaptions[style=smallbodyfont,location=grid,inbetween=]

\defineexternalfigure[enkel] [width=10cm,frame=on,grid=depth]
\defineexternalfigure[dubbel][width=10cm,frame=on,grid=depth]

\starttext

test \placefigure{}                 {\externalfigure[t:/sources/cow.pdf][frame=on,grid=yes]} test \page
test \placefigure{\input zapf\relax}{\externalfigure[t:/sources/cow.pdf][frame=on,grid=yes]} test \page

test \placefigure{}                 {\externalfigure[t:/sources/cow.pdf][enkel]} test \page
test \placefigure{\input zapf\relax}{\externalfigure[t:/sources/cow.pdf][enkel]} test \page

\stoptext

i.e. the grid option determins which way a height snaps (or is rounded);
