I wouldn't expect that ;-)

You can use gs to resize. An example:

gs -r20x30 picture.eps

I also checked the postscript output - it doesn't use the original file, even 
if the picture isn't resized. And the picture saved in the kpresenter file 
isn't the original one either.
I don't know which problems exist with embedding eps files into ps output, 
but that is the behaviour I would expect, since each conversion reduces 
quality.

I also checked the tool "psresize", but it doesn't work always and is not on 
each system installed.

kpresenter and kword combined - looks like the perfect office tool for 
presnetations :-)
