Use a temporary variable to the js-quote hook in generateQuoteMarkup.
Use an ID hook for the background image.
Optimize backgrounds with http://kraken.io.
Add text shadows.

Move second quote from chibird to unattributed section.

This quote has a source, but without an author it doesn't make
use of it. I need to fix that.
