Transparent images and w3m-image-default-background

[Antoine Levitt <antoine.levitt@xxxxxxxxx>]

Hi,

Some wepages, for instance http://www.phdcomics.com/comics.php and
http://vidberg.blog.lemonde.fr/ look awful when viewed in w3m inside
emacs, especially on dark background (set-background-color
black). Looking in the doc, I thought

(setq w3m-image-default-background "white")

would do the trick, but it doesn't change anything. Is it ignored for
some reason?

I'm using latest CVS emacs/emacs-w3m.
