[NTG-context] place figure without \placefigure

Hello, in a german text I have to place two figures and a table. If I use \placefigure they are well centered - but with french captions: Table or Figure. I dont need the captions. Without \placefigure, the figures are not centered. Is there a way ? Thanks, -- René Bastian www.pythoneon.org www.musiques-rb.org
