Our main LilyPond use case currently is images in tables; see the
attached screenshots (before – after).  Additionally, inserting such
small Gregorian neumes as inline images into normal paragraphs both
saves a lot of vertical space and increases readability.

However, I believe that having support for inline images is a good
feature for other use cases, too.

Right now, I'm successfully using the following code.

```
@tex
\gdef\raisebox#1#2{%
  \setbox0 = \hbox{#2}%
  \def\width{\wd0 }%
  \def\height{\ht0 }%
  \dimen0 = #1\relax
  \raise\dimen0 \box0 }

% Factor -0.4 is heuristic.
\global\let\imageold = \image
\gdef\image#1{%
  \ifhmode
    \raisebox{-.4\height}{\imageold{#1}}%
  \else
    \imageold{#1}%
  \fi}
@end tex
```
