How can i change the logo on a site, dynamically, with a URL field which doesn't point to an actual image but to a rendering of an image. Is this possible? I've tried this:
$thisimage = $logo_img_url. "&file=" . $_SESSION[ 'logo_img' ] . "&width=300&height=80"; variable_set( 'logo', $thisimage );
but it's not working.
Any help would be appreciated. Thanks
