Just tried this in the browser add the http:// to it http://www.secretsjewellery.com/incl...nekeBanner.jpg

and came up with a 404 cannot be found...quadruple check that the image is there as it should load from the above and it is not - spelling and case sensitive

You have this in your css background-image:url(../images/HannekeBanner.jpg) but you posted that this was hannekeBanner.jpg

Just checked and with a cap "H" it displays so the image is there...

Go back and rename on your server the stylesheet_before.css to stylesheet.orig or anything but ".css" as the system will parse all .css files in order. I believe that this is the issue
