Title: Fix empty image 'src' causing a faulty double request

Initialize the img 'src' with a tiny transparent pixel graphic rather than leaving it empty by default. This fixes a faulty double request to the containing page itself causing a 'Resource interpreted as Image but transferred with MIME type text/html.' warning in Safari/ WebKit.
