Ok so this script requires the "netpbm" package of image manipulation
programs. Anyone who builds Lilypond from source probably has it
already, but it's easy to get under Linux and Mac. for Ubuntu I do
"sudo apt-get install netpbm" and for mac "sudo port install netpbm".
I see that there's a Windows version but I've never tried to install
that because I rarely use Windows. So far the script works perfectly
for Linux and Mac OSX 10.4 (maybe 10.5 but I can't try it b/c I don't
have one). A couple of lines are different in the Mac version because
of the different image viewer and different way of invoking lilypond
at the command line.
What I find useful about the script is that it prompts the user for
the desired output resolution and format. So far I've run it
successfully at resolutions from 72 to 1200 dpi in png, jpeg, and tiff
formats. I suppose you could use any image format for which there is
a "pnmto___" program, substituting the appropriate text for the
format. The script will look for whatever format you type in there.
Note, if you want a musical example suitable for inserting in a
word-processed doc or web page, you might want to remove or comment
out the header block of your file.
Once you've saved and made the file executable (I keep it in my /bin
directory so it's in my $PATH), just do "lilyimage foobar.ly" and
enter the resolution and format when prompted.
I copy below the Linux and Mac versions. It would be cool if someone
made it work on Windows, to :)

I'm LilyPonding a piece which requires a "Notation Key". The
recipient of this notation key will be doing a bit of further
manipulation of the output. What I need to provide is, at her
preference, a PNG closely cropped so that she can then position this
graphic under some introductory text about the piece. I have been
unsuccessful at finding information about this in the docs.
If it's a single line of music,
-dpreview
could do the job. (that's what I use)
The info in AU about lilypond-book might help (inserting lilypond
output into other program), but probably won't, since it's aimed
at producing eps images. Actually, you might be able to convert
the eps to png using an external program.
Finally, you could play with clip-example, which I believe is now
in NR 3. But I'm not certain if anybody's rewritten the docs for
them -- I certainly haven't.
Cheers,
