Hello,

lots of my images are huge 200x250mm. I reduce their size with: \externalfigure[cow][width=20mm, heigth=25mm]

After generating the PDF, the pdf is very huge.

1. Can't Context put the reduced image into the PDF? 2. How can I generate one PDF version for printing (300dpi) and one for the screen (72dpi)?

I am using Context mk-IV.

no, you need something like ghostscript. In this case (if you have not problems of space and time) it's better to transform the pdf in ps with  pdftops yourfile.pdf and then apply ghostscript to the final ps (see the documentation about ghostscript)

ghostscript can do that directly with the pdf (no need to go through ps)

(also see: http://article.gmane.org/gmane.comp.tex.context/71919/match=lowres) yes, but latest ghostscript (ver. 9) sometimes fail when used
