Broken images. See screenshot. The first image, for the HTML5 project, links to this:

file:///home/nboldt/eclipse/workspace-clean45-2/.metadata/.plugins/org.jboss.tools.central/images/1206740293/images%2Fwizards%2Fhtml5.png

But that won't load in my browser.

Instead, THIS image DOES load:

file:///home/nboldt/eclipse/workspace-clean45-2/.metadata/.plugins/org.jboss.tools.central/images/1206740293/images%252Fwizards%252Fhtml5.png

Seems you need one extra level of escapes: `%252F` instead of just `%2F` for those slashes ( / ).

Could your filenames simply be images-wizards-html5.png to avoid the need for hexcode escapes?
