Apparently w4b is a search tool (e.g., "w4b anna") - brings up porn images. I have blocked it at my router level but would prefer that OpenDNS block it. THanks.

As far as I can tell W4B is a acronym for "Watch for Beauty" these are simply photos that have been tagged with either W4B or Watch For Beauty.

There isn't really any way to block these out themselves (as you said its a search term rather than a domain)

Since these images appear even with google safe search set to strict it could be a problem.

However, you could go down the route of blocking images from google, yahoo etc by adding the following domains into your always block within opendns dashboard.

Google:
gstatic.com
Bing:
mm.bing.net
Yahoo:
yimg.com
Ask:
picsearch.com

Please read the following support article before doing this
http://www.opendns.com/support/article/121

I would also point out that this will probably only reduce the number of images shown and may not block them out all together.

Failing that submitting the domains that host these images as pornographic under domain tagging (or if you prefer you can open a support ticket and list them)

I hope some of this is useful to you. (sorry i cant be of more help)

Thank you - it's at least a start!
