Limit image size

Issues containing large images are hard to view, because images are displayed at their native size.

The image already contains max-width: 100% as a style, but this does not seem to work with Flying Saucer. It seems adding -fs-fit-images-to-width does the job (https://groups.google.com/forum/#!topic/flying-saucer-users/nSCHL1TzESs)

I guess I should verify how it behaves with small images now.
