Thanks, it's clear now what is the reason of this bug.

`Info-hide-cookies-node' hides a cookie, including one optional
*trailing newline*.

The image cookies in Lilypond's Cheat sheet end with trailing newlines,
so when `Info-hide-cookies-node' hides the newline, images are displayed
in one long line.

It seems hiding the newline was necessary only for index cookies,
that after hiding would leave an empty line.

OTOH, the docstring of `Info-hide-cookies-node' says:

  Hide unrecognized cookies in current node.

So your patch uses `(not (get-text-property start 'display))' to tell
`Info-hide-cookies-node' that this cookie was already recognized and
processed by `Info-display-images-node'.

This is not just improvement, but a plain bug fix.  I suggest to install it.

Since IIUC currently CVS is read-only, you could create a bug report in
the bug database to guarantee your bug fix is not lost and fixed in the
next release.
