There are a problem with IMAGES.google.com
After the last update (to ver.0.76), there are a trash in links to websites.

For an example:
I'm have the option "Images->Rewrite links" enabled, and search for "keyword" on images.google.com:
http://images.google.com/images?q=keyword

After search, I have rewrited links:
1) direct links to images (its are ok);
2) links to webpages, which contain the images.
All links to webpages contained the such parameters att the end:
"&usg=__UyRBa5wqzU_7WNgYZyUkRUbtVzY="
so urls looks like:
http://johnbokma.com/firefox/keymarks-explained.html&usg=__UyRBa5wqzU_7WNgYZyUkRUbtVzY=
http://www.seotoons.com/2006/04/08/most-searched-keyword/&usg=__X3sYFsYqL5zRm30xBpDv6LFMVpU=
Why?
And we have links, which always will show "Error 404"....
Why this trash are added at the end?
HOW to disable/remove the unnecessary "&usg=__" paremeter from links?

(FireFox 2.0.0.14 ; all extensions are disabled, but the Customize Google is enabled).
The problem appear after update to version 0.76, but uninstalling and installing previous versions can't solve the problem already.
