Well, yes, the block is by default the width of the page,
so the border is the whole width.  It does look funny
on a graphic.

The figure element can contain any number of things
besides graphics, so perhaps you should be concentrating
on graphics within figure rather than on figure.

If the generated <fo:external-graphic> object has the
border properties, they should fit tightly to the graphic.
This works in RenderX's XEP, but the border doesn't
show at all in FOP when I do that.  If you are using FOP,
I think the imagemagik solution is probably the best.
