<Script Language="JavaScript">
function display_image(form) {
selectionname = form.imagename.options[form.imagename.selectedIndex].text;
selection = form.imagename.options[form.imagename.selectedIndex].value;
PreView = window.open("", "Preview", "toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=0,resizable=0,copyhistory=0,width=360,height=440 left=0 top=0");
PreView.document.open();
PreView.document.write("<HTML><HEAD>");
PreView.document.write("<TITLE>Preview</TITLE>");
PreView.document.write("</HEAD><BODY BGCOLOR=FFFFFF TEXT=000000>");
PreView.document.write("<FORM><CENTER><B><FONT SIZE=+1>" +
selectionname + "</FONT></B><HR>");
PreView.document.write("<IMG HSPACE=0 VSPACE=0 " +
"SRC='" + selection +
