At the moment the jumbotron background image is a load of 100K to 250K (depending on which monthly image is being used) for all browser widths - this is a large proportion of total page weight for browser widths less than 768px (e.g. mobiles): total page weight is 557K this month which includes a 239K jumbotron background image. If we produce smaller versions of the jumbotron background images and use them for narrower browsers, page weight should drop significantly.
