There is a new Google manual action that you need to be aware of named "image mismatch." This manual action is when your images on your site don't match what Google is indexing and displaying in their search results. https://support.google.com/webmasters/answer/3394137
My sites visitors from google images results turned now to 0 because i am using this plugin to protect my sites from hotlinking, google is forcing users to allow them to hotlink to photos or to get 0 visitors.
No option but to allow Google to steal my bandwidth in return for visitors, and I want to keep the hotlinking active from any other sites on the internet, but i have no idea how to add Google images to be in (allow this domain) section in the plugin part, adding google.com is not enough since there is tons of domains ended with ".uk , .fr , .de, and etc.)
Any help is very appreciated.
