Wikipedia photos render as placeholder in GD

GD 1.0.1 on Linux Fedora 15,
It used to work fine before (I guess). The images don't display anymore.
I use
http://en.wikipedia.org/w
http://fr.wikipedia.org/w
Prefs > Newtork > disallow content ... is unchecked.
Right: Images display as placeholders.

Red square: I am using random country flags. I would like to use the Wikipedia icons. What's the path, on Linux, of the Wikipedia GD icons. Thanks.
