My web page uses visual images am I the only one paying the Licence?
No. You are required to have a License, as is your Internet Service provider, your Telco whose phones connected to the web and anybody else contributing to the use of  the patent. All search engine portals and web sites that have search facilities and images will require separate Licenses.
