Plugin stopped working

Hi,

It looks like the plugin stopped working worldwide? Google made some changes and now the plugin does not display the watermark. Also, the images appear smaller in the search results- looks like a way how Google got around the workings of the plugin.

Is there any solution to this? What do plugin authors think happened?

Thanks
