This handler might do what you suggest.  It is completely untested, but 
might give an idea of what should be done.

on setJPEGdpi @jpeg, dpi  -- dpi less than 256
   put numToChar(1) into units -- dots per inch
   put numToChar(0) & numToChar(dpi) into encodedDPI
   get units & encodedDPI & encodedDPI
   put it into char 13 to 17 of jpeg
end setJPEGdpi
