What I do is that most of my source images are in .eps, and for PDF
output, I convert from .eps to .pdf.  Thus no density problem arises.
'convert foo.eps foo.pdf' works great.

I guess that doesn't help you if your source images are .png however.

The problem is that whenever you convert into PDF format there is a
density being set implicitly -- default is 72x72.  I bet you already
know that.

I dunno, 'convert foo.png foo.pdf' works for me, but I haven't tried
embedding that.

I just noticed the EPDF format.   Hmm.   Maybe that is what we should
be using?
