[NTG-context] \IncludePicture in SimpleSlides

Hello, I have tried the simpleslides module. Starting with it is very nice. I have get some trouble with \IncludePicture. Running : ConTeXt ver: 2012.12.28 20:30 MKIV fmt: 2012.12.29 int: english/english \IncludePicture [horizontal] [riviere] {La Dumbéa} do not work. Maybe that problem is new (process succeded a few time ago). If I use \externalfigure, no problems. Best regards, Roland
