On the main page of bugzilla.gnome.org there is an image of a bug:
I do not like that image. Could someone please design a better one and attach it to bug 339216?
Another thing I hate is the color used for quoted text (#ad7fa8). I chose that color so that I could make the first person who complained responsible for giving a better one. Unfortunately no one complained. Still want a better (non-blueish) color.
