Hi,

the code:

.\" --------------------------------------------------------------------
.\" IMG [-R|-L|-C] filename [width] [height]
.\"
.\"   Include an image of any type (will only work for -Thtml).
.\"
.\"   Alignment is centered by default (-C).
.\"   Default value for WIDTH is 1i.
.\"   If HEIGHT is not given, WIDTH is used as the height.
.\"
.de IMG
.  ie \\n[www-html] \{\
.    ie '\\$2'-R' \
.      HTML-TAG ".right-image"
.    el \{\
.      ie '\\$2'-L' \
.        HTML-TAG ".left-image"
.      el \
.        HTML-TAG ".centered-image"
.    \}
.    nr www-width 100
.    if !'\\$3'' \
.      nr www-width \\$3
.    nr www-height \\n[www-width]
.    if !'\\$4'' \
.      nr www-height \\$4
.    HTML <img src="\\$1" width=\\n[www-width] height=\\n[www-height]>
.  \}
.  el \
.    nop \[la]\f[C]\\$1\f[]\[ra]
..

emits a series of `html-tag's to post-grohtml. The first tag in the
context of this macro is the alignment the next paragraph must take.
So when the:

.    HTML <img src="\\$1" width=\\n[www-width] height=\\n[www-height]>

is interpreted it generates an html-tag containing raw
html. post-grohtml now checks so see if the paragraph alignment has
changed. If so it shuts down the previous paragraph and opens up the
requested aligned paragraph. After which it emits the html image.

hope this helps,

Gaius
