[NTG-context] figure can not be found error

I am attempting for the first time to import a figure into a ConTeXt document and am getting "figure 0481c can not be found." I am using TexLive on a Windows Vista system. I thought I was following the manual but apparently am doing something wrong. Here is the relevant code: %file 0481c.tif is located in c:\BookLayouts\Wisconsin\photos \setupexternalfigures[directory={c:/BookLayouts/Wisconsin/photos}] \useexternalfigure[ladies][0481c][width=3.127in] %after \starttext \placefigure[left]{none}{\externalfigure[ladies]} Tom Benjey Tuxedo Press 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey
