    Hi There

    I am in charge of the opendns filtering in a number of schools. If the nude/pornography images cannot be isolated and blocked through the image search. Then how do I block all images as you said above.

    "....not something OpenDNS can block without blocking Google Images entirely."

    You can add the domains to your block list to block images. The domains that Google uses to store their images are as follows:

    encrypted-tbn0.google.com  
    encrypted-tbn1.google.com  
    encrypted-tbn2.google.com  
    encrypted-tbn3.google.com  
    encrypted-tbn.l.google.com  
    tbn.l.google.com  
    gstatic.com

    Please note that if you do add these domains to your network's block list, you do risk filtering out other images and graphics that Google uses to support their various services.

    Thanks Chris

    This is a great start. If it blocks other images too then so be it. At least this will give them a starting point and we can discuss the matter with them after they calm down. 

    I'll try adding these now and let you know we get on. BTW. I came across the following article below which might be worth looking at too.

    Hi Chris

    I was trying to implement your suggestion and I received an option that I wasn't expecting. I have included an image with a screen shot. I am going to select "Block encrypted-tbn0.google.com — just the individual domain" for the moment and see what happens. If you guggest me to sleect "I'd rather block categories of websites that include encrypted-tbn0.google.com" instead, then I will go back later and change it.

    You would want to select "Block encrypted-tbn0.google.com — just the individual domain" .  :)

    The article you linked to is pretty outdated, to say it diplomatically and is related to another (unspecified) application running locally...

    And yes, this "Block encrypted-tbn0.google.com — just the individual domain" is the right option.

    rotblitz is correct the domains are outdated, as Google has changed how they store their images. However, you might still have some luck with blocking the images using the aforementioned domains.

    Hi Again

    That seems to work some what but not completely. Some images still load. About a dozen or so. And the rest of the image place holders appear blank. I have attached an image.

    If any of these place holders are clicked they mostly show up blank. However there are a few that still show up.

    These pictures are not really pictures, but data URLs in the web page's code. Therefore you cannot block them unless you block the domain were this web page is hosted on. As this seems to be hosted on www.google.com, you would block Google as a whole then. A more realistic way to go is to use Google's SafeSearch feature or an ad blocker where you generally block those data URLs.

    I actually chose 'block categories of websites' not individual domain. How can I go back and 'fix it'? I am now blocked from yahoo completly. Thx

    Hi Prudog. I actually did the same in error when trying to implement the above suggestions and I was scratching my head as how to reverse it. As far as I remember I used the same URL and set it for Allows Allow. This reversed the rule which allowed be to do it again and this time selecting a different method when offered the choice.

    BTW. This didn't work for me. They can still see the thumbnail images in the google image search and they in turn go large once clicked. There are not as many as before but even one is too many in a school of teenagers.

    Can you keep me informed as to how you get on. I have been looking for a solution here for a while now and no joy yet. I know that I could get a new router and use the blocking features in its control panel. However if that was the route I wanted to take, I would have done this originally instead of going down the OpenDNS route.

    OpenDNS bills itself as a Family friendly product saying it blocks pornography websites. And that is with its free product. As we are paying customer you think that it would be pretty much guaranteed. But it's not. I have read many forums and the defenders of OpenDNS say that it does not block websites only DNS.

    But this does not make any difference. If they advertise that their product is "the absolute simplest and most straightforward way for parents to protect kids from the bad stuff online" & that the "service blocks pornographic content, including our “Pornography,” “Tasteless,” and “Sexuality” categories"  (http://blog.opendns.com/2010/06/23/introducing-familyshield-parental-controls/) then this should be the case accross the board and not everything except one big gapping whole in their defence that they all seem to know about for quite some time now.

    If someone else (not the originator of the material) is getting the content through their defences,  the OpenDNS should have an option to block these. So if Google images is allowing the material through then there should be an option in OpenDNS to block google images entirely.

    If anybody at all can get back to ma about this I would appreciate it. We are in charge of 17 schools all of whom are paying OpenDNS for their online security. I have been on to Google Apps about this too as each school has a Google Apps for Education account. However there is no way of pushing out the required security setting to google Chrome. 

    Only one of these schools actually has a proper server, so there is no Active Directory. Therefore any "Safe Search" setting that I may put in place can be overwritten by the user.

    Any help or suggestions would be welcome here. This is not an OpenDNS bashing session. I genuinely want to get a solution here that really works and without the purchase of new routers.

    You'll have to use Google's SafeSearch or to block Google as a whole with OpenDNS.

    OpenDNS can block only domains, because DNS generally doesn't know about images or pages or videos or any other objects.

    If you want to exempt a site from category blocking, you had to whitelist the related domains. 
    These should be found at https://dashboard.opendns.com/stats/all/blockeddomains

    I blocked the domains Chris listed above and I'm still getting image results coming through. How do you figure out what domain they come from? Is there a resource that tries to keep the domain list up to date somewhere?

    Thank you kindly for your help.

    The problem is when you say you block porn and then we can clearly see thumbnails of porn that's not really blocking porn the way people think it is. As a mom of 4 kids and a wife of a husband who has had a problem with these sorts of images it is very upsetting that I'm trying to block everything I can yet there still is this much porn getting thru. :/

    Unfortunately, since the search images are imbedded in Google's URL, you can only block the images by blocking Google as a whole. Other search engines for example, "Bing", host all of their explicit images on a different domain which is easy to block.

    A good idea.  Now do it!  ;-)

    Ah, and a hint to OpenDNS:  Refrain from advertising that you can block "porn" (adult content).  You can't!  And you're raising wrong expectations with those moms and dads, and this is with frustration afterwards: "we can clearly see thumbnails of porn that's not really blocking porn the way people think it is".

    Say that you can block domains/hostnames which may or may not host "adult content".  Maybe hard to understand for a todays average naturally dumb user, but honest and open.  There may be better wording though to explain it.
