Hi Heinz,

Thanks for the example and output. Certainly a bug, in fact I think it
may have become broken when grohtml was rewritten. The left-image,
right-image, center-image etc has no effect, as you've pointed out,
and I'm beginning to think this should be altered to a .left-para,
.right-para, .center-para or similar as it was intended to effect the
surrounding <p align=> rather than the <img align=>. The later being
served by MPIMG. You're right about the inconsistency between
documentation and macro set - feel free to fix the macro set to behave
as per documentation. (Though the paragraph alignment won't take
effect until post-grohtml is modified). You can test to see that the
new macro set works if you supply the -Z option to groff and eyeball
the ditroff output (which will include your html-tags as specials in
your output).

hope this helps,

Gaius
