References to gravatar images are generated with HTML and XML outputs only
as these are the only formats where referencing gravatars makes sense
right now. The HTMLEmbedded format, for example, does not link to any
gravatars as that format prohibits the use of external links.
To accommodate the new images; the width of the generated HTML page has
been slightly increased. However, the HTML page should still fit on a
1280 display.
