  If possible, the probable best way to handle the above case would to not 
mess with the DPI until the print function is called.  Then, instead of 
resizing the image in the document, have a print export function which, 
during the conversion to postscript (or whatever) handles reducing the size 
of the images (if needed) as they are included by checking to see what the 
printing resolution is and rescaling everything to that resolution (since 
any more would be pointless in any case, being beyond the printer 
capabilities.)  Or on a print to file, allow the author to select an output 
resolution.  That way, anyone working with the image in the document doesn't 
lose anything to rescaling until print time comes, and if they want to edit 
something and reprint they aren't stuck with a bunch of images which have 
been resized in the document.

  Hopefully I've been coherent. :-)  I don't know if this type of thing is 
possible, but if so it would probably be a big help when printing over a 
network or fun things like that, as well as saving harddrive space and 
making less work for the printer itself.  One last thought.  I don't know 
much about postscript, but is it possible to internally (within the 
postscript file) make use of the postscript data on an image elsewhere in 
the document?  That way, with elimination of duplicate postscript data, 
would undoubtedly be the smallest possible file size.  (i.e., the image 
stored in the largest size necessary in that document for the printing 
resolution being used, and otherwise just references to that data?)

Sorry if my ignorance has nullified any helpfulness as far as these 
suggestions are concerned.

Best,
C Y
