Hey guys, need a lil help!

On our network were trying to block Google Video Search results.

We have blocked video.google.com etc etc, but when you do a web search and then click on Videos, it shows the results, so if someone was to search for something, shall we say, naughty, it shows the thumbnail of that video, the video itself is blocked, but it still shows the thumbnail, and turning off safe search makes it even worse as you can imagine!

Does anyone have any idea of the URL we need to block these thumbnails? We have done Image results fine, just really struggling with videos.

Were using Websense Hosted Security, waiting for them to come back to us, but cant find the answer anywhere yet, so thought I would ask here for any guidance!

Cheers!

Yeah those pictures aren't really URLs... the only thing in common seems to be

data:image/jpeg;base64,/

Then a big scary string of numbers. This is one example:

However, google video search has a unique value in the URL, which you may be able to block URLs that contain the following:

tbm=vid&source=vgc

Yeh, its very strange, been testing with different browsers and IE9 DOES block the images, as it renders th epage differently, the thumbs with IE9 come from ACTUAL URL's, for example:

http://img.youtube.com/vi/zGii3arUoY4/default.jpg

So the images get blocked as youtube is blocked. FF, Chrome and IE8 all render them with

data:image/jpeg;base64,/

It does appear we will have to block Google and use Bing instead, we have been able to block those videos and images with ease.
