\startmode[presentation]
\useexternalfigure[COW][cow.pdf][height=5cm,width=3cm]
\stopmode
\startnotemode[presentation]
\useexternalfigure[COW][cow.pdf][height=5cm,width=5cm]
\stopnotmode
or
\startmode[presentation]
\definemeasure[alternativewidth][3cm]
\stopmode
\startnotmode[presentation]
\definemeasure[alternativewidth][5cm]
\stopnotmode
\useexternalfigure[COW][cow.pdf][height=5cm,width=\measure{alternativewidth}]
