Seems like this script does a top level document search for nodes to apply it's PNG fix. This can really hurt performance for sites that have complicated layouts. Sometimes it's best just manually code your own png fix solutions (fix exactly the image and div nodes you need for each page, rather than conducting a document.getElementsByTagName.. sweep)
