Yes, I tried that and it doesn't work.  I tried using that example in the admin tool (the one mentioned above) and the image doesn't change.  I tried putting the full path, http://myserver.com/images/mylogo.jpg, and that didn't work either.  I'm assuming that this logo image will replace the CuteChat logo, but it doesn't even show a broken image when i put a bad path in the text field.  I'm also assuming hat the image should go in the application directory called "cutesoft_client/cutechat/images/"
