How can I disable third party cookies?
Knol allows authors to use images from remote websites. Some users have expressed concern that this may expose visitors to being tracked by those third parties. Note that this is not an issue specific to Knol; the use of third party images is widespread on the internet. The Wikipedia page on HTTP Cookies has an introduction to this topic.If being tracked is a concern for you, you may choose to have your browser block third party cookies.
Note that if you block all cookies, you will be unable to use most web services that require you to log in. But blocking third party cookies is rarely disruptive.

But when you next visit the website, only first-party cookie information is sent to the website. Third-party cookie information isn't sent back to the websites that originally set the third-party cookies.

The default setting is to accept cookies only from sites you navigate to. This excludes third party cookies.
Can third parties see my IP address?
Yes. If a knol contains an image, then your browser sends an HTTP GET request to that site. It is site could log your HTTP address. This is a basis for techniques as simple as Hit Counters and as complex as Google Analytics.What about author portraits and thumbnails in search results?
Thumbnails and author profiles are hosted by Google, and do not involve request made to third party sites.References

A suggestion
I suggest google to accord with sites that have free photos, videos and tables, etc., and create a knol with a list of these sites.
This list will growth because the owners of these sites will be that they will be known because the authors of knols will use them.
