Subject: Absolute positioning of \startcombination... \stopcombination

Hi,
I would like to position a combination of images where the centre of the
combination coincides with the centre of the text area of a page. In the
example below I have made the combination into a layer thinking that
this would be the easiest way to position it where I wanted. However to
position in the centre of the page I would need to know the size of the
combination and use this to calculate the x and y values for positioning
of the layer. I have looked at the Wiki page on image size of
combinations but still cant figure out how to do it. Any suggestions on
how to go about this or is their a better way?

Thanks
