Hello

I try to use layers to position a figure on top of the leftmargin area. I
use code like the following:

    \definelayer[MyLayer][option=test]
    \setupbackgrounds[text][leftmargin][background=MyLayer]
    \setlayer[MyLayer][x=0cm,y=0cm]
    {\externalfigure[cow][width=2cm]}

This image get's repeated every page but I only want it on the first page.
The parameter state=start does not change anything. Is there a way to
disable the layer on the next page. Also there seems to be a bug with
\showframe. When I use this command my figure is only displayed on the
first page (as desired).
When I use

    \setupbackgrounds[page][background=MyLayer]

this problem does not occur. But I have to shift the figure to place it in
the leftmargin.

I tried to use another concept like

    \definelayer[test]
    \startuseMPgraphic{oeps}
    register ("somepos-1",0cm,0cm,center currentpicture) ;
    \stopuseMPgraphic
    \setMPlayer [test] [somepos-1]
    {\externalfigure[cow][width=2cm]}
    \getMPlayer [test] {\useMPgraphic{oeps}}

but that does not seem to work at all.

Thanks for any help

Cheers,
Reza
