Sling website CSS makes images too big

At http://markmail.org/message/kseatjzm2rcwxoj7 Dan Klco mentions incorrect zooming of images on the Sling site - I'm creating this issue so we can attach screenshots, as the behavior might be different on various browsers.

I'll attach a bertrand-chrome.jpg screenshot which shows the results on my Chrome 35.0.1916.114 browser on macosx, displaying http://sling.apache.org/documentation/bundles/osgi-installer.html - the image does get very big but not over 100% width of its container in my case.
