Here is a minimal example that better describes my problem.
It seems to depend on the size of the image. 30 mm and 40 mm width 
works, 35 mm does not.
I have not tested height, although the image I want to use would be 
portrait format.

\setuplayout[grid=yes]
\setupinterlinespace[line=15pt]
\starttext
\input{knuth}
\startlinecorrection
\placefigure[left, none]
[]{}\externalfigure[cow.pdf][width=40mm]
\input{knuth}
\stoplinecorrection
\stoptext
