Hi!

I am using groff 1.23.0 and the mom macro package that comes with it.

When I try to embed an image with a centered caption which should be rendered
below the image and centered (the default, as I figure, if I read the
documentation correctly), all I can produce is a caption set in flush left
(sorry, if this is wrong terminology - what I mean is: left aligned):


.DOCTYPE DEFAULT
.PRINTSTYLE TYPESET
.CAPTIONS IMG FONT I SIZE -1 COLOR darkgrey QUAD CENTER
.CAPTION_AFTER_LABEL ALL

.START
In the following picture, you can see a marvelous view which is to
be had on the tour:
.PDF_IMAGE IMG_4025.pdf 160p 120p CAPTION "View of the Raetikon Group
approximately two thirds along the way."
.PP
It can be experienced somewhat into the tour, about two thirds along
the way.


You can see the rendered result in the pdf attached to this report.

When I remove the .CAPTION_AFTER_LABEL the caption is rendered above the image
and is centered. I've attached that document as well.

Did I missinterpret the intended behavior? If so, is there a way to achiev a
centered caption  _below_  the image?
