When using the plain macropackage and MetaPost figures, I use epsf or
supp-pdf, depending on whether I'm making a dvi or pdf:

                                  % here we test to see whether we're doing
                                  % postscript or pdf:
  \ifx\pdfoutput\undefined
          \input epsf	
          \special{papersize=11in,8.5in}
  \else
          \input supp-pdf			% mp support for pdftex
          \pdfpageheight=8.5in		% landscape letter pagesize
          \pdfpagewidth=11in
  \fi

... and another conditional part later where the graphics are loaded.

I haven't done raster graphics inclusion, but if you aren't using a
fancier macropackage like ConTeXt or LaTeX, then you'll probably need
similar conditional graphics code too.
