I have not seen how you have set up your site, but you can try to locate the div that contains the content area and add somehting like this in the index.php file(marked with red:
<?php if ($tmpTools->isIE6()) { ?>
<script type="text/javascript">
var siteurl = '<?php echo $tmpTools->baseurl();?>';
window.addEvent ('load', makeTransBG);
function makeTransBG() {
makeTransBg($('ja-header'));
makeTransBg($$('h1.logo a'));
makeTransBg($$('#ja-mainnav img'));
makeTransBg($('ja-footer'));
makeTransBg($$('#ja-footer img'));
makeTransBg($$('#the contentdiv img'));
}
</script>
<?php } ?>
Also replace “the contentdiv” with the name of the div that have your content.
Or maybe try out something like this(this might be easier for you to try out first:
<?php if ($tmpTools->isIE6()) { ?>
<script type="text/javascript">
var siteurl = '<?php echo $tmpTools->baseurl();?>';
window.addEvent ('load', makeTransBG);
function makeTransBG() {
makeTransBg($('ja-header'));
makeTransBg($$('h1.logo a'));
makeTransBg($$('#ja-mainnav img'));
makeTransBg($('ja-footer'));
makeTransBg($$('#ja-footer img'));
makeTransBg($$('img'));
}
</script>
<?php } ?>
