Converts images to data-uri (base64, image2html) and embedds them into html in a bulk/massive way, to make both html pages and html newsletters that are more efficient to download and that do not look unprofessional when (owing to privacy settings on the email reader) the associated images are not downloaded. In addition, it helps one into reducing the size of images by reducing their color count in a professional/unnoticed way. The installable version of the app is easier to setup, because it creates shortcuts.
