[NTG-context] adjust width of text automatically

Hi, Is it possible to place one box beside another, both with the same height, one box with an image of unknown width, and the other uses the remaining width. I've tried this, but without success: --8<---------------cut here---------------start------------->8--- \starttext \bTABLE[offset=0pt, height=7cm, textwidth=\textwidth, option=stretch] \bTR \bTD bla bla bla bla bla bla bla bla bla \eTD \bTD \externalfigure[hacker][height=7cm] \eTD \eTR \eTABLE \stoptext --8<---------------cut here---------------end--------------->8--- If yes, how? If no, then I'll try to get the width of the image with img.scan() ... TIA for any hints! -- Peter
