From: King, Peter R on
I have a bitmap image (.bmp file) - call it pict - that I wish to use as the background for some graphics. I do this with

Graphics[Table[Point[{x, 50 Sin[2 \[Pi] x/100]}], {x, 0, 100}],
Prolog -> Inset[pict]]

(the actual graphics is more complicated than a sine curve but never mind).

Now if I just display the graphics by typing pict I can rescale this by clicking on the image and dragging the corners of the orange box. However when I overlay the graphics onto the image (as above) and try to drag the box it rescales the plot but not the background image. Is there any way I can link the two together so I can rescale by dragging the cursor? I tried GraphcsGrouping but that didn't get me anywhere.

I am using version 6.0.3.0

Many thanks.
