Generating .png files with Lilypond

[Peter Kestens]

To create graphical files from a Lilypond file in Windows, I know only this 
rather complicated way with right click on the Lily icon, properties and then 
adding --png in the command phrase for starting Lilypond.  Is there an other 
way (less complicated) or is it possible to provide in the program "something" 
that allows easy creating .png files?

Thanks a lot
