Hi John,
wrote my first mail to fast, youre already use t:script :-).
as i wrote in th first mail the body of t:script is rendered inside hrml
script tags, and
<!--[if lt IE 7.]>
<script defer type="text/javascript" src="js/pngfix.js"></script>
<![endif]-->
is no valid javascript :-(.
try this:
<t:script onload="applyIePngFix();">
function applyIePngFix() {
// maybe better IE recognition needed
if (!window.all) {
return;
}
var arVersion = navigator.appVersion.split("MSIE")
var version = parseFloat(arVersion[1])
if (version < 7.0) {
return;
}
if ((version >= 5.5) && (document.body.filters))
{
for(var i=0; i<document.images.length; i++)
{
var img = document.images[i]
var imgName = img.src.toUpperCase()
if (imgName.substring(imgName.length-3, imgName.length) == "PNG")
{
var imgID = (img.id) ? "id='" + img.id + "' " : ""
var imgClass = (img.className)
? "class='" + img.className + "' " : ""
var imgTitle = (img.title)
? "title='" + img.title + "' " : "title='" + img.alt + "' "
var imgStyle = "display:inline-block;" + img.style.cssText
if (img.align == "left") imgStyle = "float:left;" + imgStyle
if (img.align == "right") imgStyle = "float:right;" + imgStyle
if (img.parentElement.href) imgStyle
= "cursor:hand;" + imgStyle
var strNewHTML = "<span " + imgID + imgClass + imgTitle
+ " style=\"" + "width:" + img.width + "px; height:"
+ img.height + "px;" + imgStyle + ";"
+ "filter:progid:DXImageTransform.Microsoft.AlphaImageLoader"
+ "(src=\'" + img.src
+ "\', sizingMethod='scale');\"></span>"
img.outerHTML = strNewHTML
i = i-1
}
}
}
}
</t:script>
I cant test, because i'm working on linux, but this should do.
you can also put the code into a file e.g. js/pngfix2.js and use it like
<t:script onload="applyIePngFix();" file="js/pngfix2.js"/>
Regards,
Volker
