Then, all that's left is to shrink those large images on your page (by giving them an explicit width/height attribute that's smaller than the actual dimensions), and adding the CSS class "expando" to them. For example:

the simple answer is that you need to make your image position:absolute; with a z-index greater than the surrounding items and put it in a relatively positioned container.
