Notes=Syntax is divided by two parts <strong>url:logo</strong><br />URL can be: flat url (but only from root), single php file name, category code or a number eg. for forum sections and topics (look for logochanger.config.gif in plugin archive to see example configuration). In logo part, all paths can be from root or from skin selected folder. So you can use logo with path from root to skin folder (eg. skins/myskin/img/mylogo01.jpg) or you can use logo without path at all (then current skin folder will be used eg. mylogo01.jpg or img/mylogo01.jpg) Don't use full paths (with http://) in any of url:logo. If some url/php-module/category/fsection/ftopic was not specified, then default logo will be returned.
