Content filter does not filter pictures on Google search

Hello, I have a USGFlex 200 with ContentFilter (WebFilter & DNS-Filter) running in a school environment.  Filter categories (pornopgraphic content and explicit nudidity) are activated.
Filtering works fine for URL's (p.e. youporn.com), but not for picture searches on google.com (explizit pornographic pictures are shown).
Is this a normal behaviour and can it be adapted? I want to have all pornographic content to be filtered.
Thanks & regards, Chris

    Hi @chrisx
    Unfortunately,It cannot be implemented,
    When search picture on Google, the client just connect a single valid URL and there are no others invalid URL handshake.
    Safe search on your browser may reach the requirement.
