Image blockers in search engines?

This one is the best: http://www.pluckeye.net/

 

One product I like is SafeDNS. You can get their basic service for free. It blocks bad domains and can force a safe search for search engines. A good way to use it is to set up for your home router. This doesn’t protect you away from home but is good in that it works for all devices using the router. I look at it as one of the many tools you may want to employ.

I use the firefox add on "Blocksite", It lets you pick the sites you want to block.

It's pretty good, And Free

 

For such purposes, I second the first suggestion of this thread.

Pluckeye is specifically made for blocking videos and pictures. It is also highly customizable, so you can play with the settings until you are satisfied.
