Well, I use ImageMagick-4.2.9-3 and GNU Ghostscript 5.50 (2000-2-13).
To convert postscript, I use the epstopdf (for vector images) or
epstopng ( for bitmaps ).  epstopng is a slightly modified version of
epstopdf, which uses -sDEVICE=png256 and "-r<a>x<b>" to set the DPI.

So, to include a bitmap in 150 DPI in pdfjadetex, I use the following
commands:

 $ convert -density 150 dx_lang.png dx_lang-conv.eps 
 $ epstopng --dpi 150  dx_lang-conv.eps

This gives me a dx_lang-conv.png file that I include in the SGML
source document.  Works fine for us.  I think that Camille has some
problems using ImageMagick 5.
