The simplest way to do this is with imageData. Something like the
following should do the trick (untested):
on mouseUp
put 100,100,180,180 into theRect --or whatever
set the rectangle of image 1 to theRect --original image
set the rectangle of image 2 to theRect --thumbnail image
set the imagedata of image 2 to the imagedata of image 1
set the height of image 1 to the formattedHeight of image 1
set the width of image 1 to the formattedWidth of image 1
end mouseUp
Note that the two images need to have the exact same rectangle, or the
second image will show distorted garbage, or nothing at all.

PS: I used this in Malta during my presentation, but also transfered
the imagedata over a socket. So you could theoretically even save the
imagedata to a file, for later retrieval.

If this has already been written up somewhere, could someone point
it out to
me? The imageData dox entry describes what it is but not really how
to use
it.
