Hi Andreas

Hmm,, When I try this script, it actually creates  a much larger, nasty 
looking PDF, without selectable text.

Also, the script wouldn't work with gsc, but did with just gs.

I'm using Ubuntu Hardy Heron, with latest GS,  etc.

The original PDFCompress script that is on the wiki 
http://wiki.scribus.net/index.php/Web_optimised_PDF works excellently 
still for me, and reconstitutes the PDF into an indexable Text too. It 
really shrinks the PDF from say about 1MB to about 200kb, usually that 
level of compression, without messing about with reducing image 
resolution either.

It uses much the same techniques, so I'm confused why there is so much 
difference in functionality.

Kind regards
