Just thinking you could try using custom tags in the admin, put the image url in there and then just do something like –
Create custom tag called BGIMAGE with the image url as the value. Then use this in the head of the header file….
<?php $key = "BGIMAGE";
$BGIMAGE = get_post_meta($postID, $key, true);
if(!empty($BGIMAGE)) { ?>
<style>
body {
background-url:('<?=$BGIMAGE; ?>');
}
</style>
<?php } ?>
Hope that helps.
