hm, strange, it seems that
externalfigure is redefined
This is ok

\starttext
\startMPcode
def externalfigure primary filename =
if false :
rawtextext(\externalfigure[  filename  ])
else :
image (
addto currentpicture doublepath unitsquare
withprescript fg_name=  filename ;
)
% unitsquare
% withpen pencircle scaled 0
% withprescript fg_name=  filename
fi
enddef ;
draw externalfigure hacker.jpg xscaled 30mm yscaled 20mm ;
\stopMPcode
\stoptext
