A quick little PHP script

I have a hosted PHP website in which I do not have access to the PHP code.? I do have access to a CMS that will allow me to drop PHP code on any page I wish (snippets).? This includes a page footer that is on every page on the site. What I am looking for is a PHP script that will remove a graphic and link from the bottom (footer) of my website. <[login to view URL]> The Link "Real Estate Webmasters" The graphic and logo associated (and link)
