%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\definecolumnset
   [main][n=2,distance=.5cm]

\starttext

\startcolumnset[main]
\dorecurse{10}{\input tufte \par}

%\startfiguretext[top]{%
%  hi there}{\externalfigure[picture][width=1.5\textwidth]}
%\startfiguretext[top:2]{%
%  hi there}{\externalfigure[picture][width=1.5\textwidth]}
\startfiguretext[tbrl:2]{none}{\externalfigure[picture][width=1.5\textwidth]}
Here is some text about picture. I want put this text with picture
on the top or button of this page.
\stopfiguretext

\dorecurse{10}{\input tufte \par}
\stopcolumnset

\stoptext

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I use:
------
