Ah, sorry.

But IMO the foreground of an image shouldn't be affected by the
current face's foreground.  Images should come with their own colors,
and be displayed like that.  I think in the context of the discussion
that led to this bug report it's actually almost a must: we want
images with attractive colors to serve as the icons, we don't want
them to be affected by whatever face happens to be nearby.
