hi, you'd have to contact the website where the unwanted pic appears about this. we don't control the content on the internet ;-)

There are other things that need attention.

The System Details list next to the question shows that you run an older Firefox 46 version that is no longer supported with security updates.

• User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0

Always update Firefox and Add-ons to the latest versions to get all security fixes.

Please update to the current Firefox 51.0 release.
