I have done something similar by putting a while loop around the bulk
of the processing.
e.g.,
while(!mouse.button ne 4) do begin
cursor, xp, yp
; other assorted processing
endwhile
You can now click forever, or until you press the right mouse button.
Whichever you prefer.
You now need to get a bit clever about handling the multiple clicks.
Enjoy.

Another option would be to put the image in a widget, and to have a
mouse click event handler that modifies the image, re-displays it and
save it... the only advantage is that you do not have to do a
right-click to stop. The disadvantage is that you have to manually close
the window....
