Here's a macro to do it. It scans the centre lines of the image looking for 
the smallest dot it can find, so it can make mistakes with some images if 
they're made up of large blocks of color, ie if the centre lines don't hit a 
pixel sized color change.

To change the image type you'll need to update the macro, as I couldn't get 
it to work as a variable. It's currently set to 'jpeg'. For bmp use 'sys'.
Takes about a second to scan a 640x480 image.

Hope it's useful,

Regards,
Chris B.
