This is what happens to me: I use PNG for screenshots for both PDF and 
HTML output formats. Then I wanted to insert a diagram exported in EPS 
format from the editor for PDF output, and PNG for HTML. Obviously I 
cannot use the PNG for PDF because it is bad quality.

As PDF can embed vector graphics in it, this is the insurance that best 
possible quality, in terms of resolution, will be achieved at print time.

As I don't want the processor to exclude all PNGs for PDF (because of 
screenshots) I had to use the following:

       <mediaobject>
	<imageobject>
	  <imagedata align="center" fileref="images/animation-fig.pdf"
	  format="PDF" width="15cm"/>
	</imageobject>
	<imageobject>
	  <imagedata align="center" fileref="images/animation-fig.png"
	  format="JPG"/>
	</imageobject>
       </mediaobject>

and exclude JPG for fo output in customization layer...

Hope it's clear now,

Camille.
