If you need to include fonts to your publications (e.g. for printing 
houses), using latex and dvips (or possibly even pdftops) may still be 
needed, and this requires additional processing. I agree that pdflatex 
or xetex are the best alternatives for _online_ pdf publishing and you 
should always use vector gfx if possible.

to do the initial conversion, use imagemagick convert (installed in 
jalava, etc). e.g. with 300 dpi originals:
convert ín.png -density 300 out.eps

however, to make sure the resolution is preserved in the final pdf 
(assuming you are creating one), you should note the settings in 
ghostscript as well since this does affect the information contained in 
images regardless of the resolution used in the original conversion.

for example, when using PREPRESS setting in ghostscript ensures that all 
the images are in uniform resolution (possibly lower than the 
originals), suitable for printing press:
ps2pdf -dPDFSETTINGS=/prepress -dCompatibilityLevel=1.4 
-dMaxSubsetPct=100 -dSubsetFonts=true -dEmbedAllFonts=true in.ps

you can replace the PREPRESS setting with DEFAULT to keep the 
(bitmap-converted) images in as high resolution as possible, but this 
does not include fonts.
