given that you have figures like picture-number you can define a conversion
like:
\def\HandDrawnRomanNumeral#1{\externalfigure[picture-#1][height=1cm]}
\defineconversion[handdrawnromannumeral][\HandDrawnRomanNumeral]
but, this is probably not what you want, so better is:
\setuphead[chapter][numbercommand=\NumberCommand]
\def\NumberCommand#1%
{\externalfigure[picture-\currentheadnumber][height=1cm]}
we cannot use #1 because it is more that the number; \currentheadnumber is
available in the latest version
