Hi Andries,

thanks for the bug report.  The bug in still present in the current
cvs, in fact the current cvs ignores any generated images in the .TL.
iirc this is because images are not allowed in-between title tags.

However a work around would be to use the .HTL macro to set the
text of the html title tag and then to produce a graphic title using
eqn.  Ie:

.EQ
delim $$
.EN
.HTL
Chain calculus
.LP
.HTML-IMAGE-LEFT
Chain calculus in the geometries of types $A sub n$, $D sub n$, $E sub
6$,
$E sub 7$, $E sub 8$
.HTML-IMAGE-END
etc

regards,
Gaius
