Lintian tag information: info-document-missing-image-file (type: warning)

Description (from lintian-explain-tags)

This info document contains an "[image]" but the image file it specifies
is missing. Texinfo @image{} becomes

[image src="filename.png"]

in the .info. Emacs 22 and up info mode can display this in a GUI if
filename.png is in /usr/share/info or if the src gives a path to the file
elsewhere.

If you put an image file in /usr/share/info then please name it like the
document so as to avoid name clashes. Eg. foo.info might call an image
foo-example1.png. If upstream does not do this already then it may be
easier to sed the src="" to a path elsewhere, perhaps to share with an
HTML rendition under say /usr/share/doc/foo/html/.
