If you hate the new Google images pages there is a "switch to basic version" link at the bottom of each page that will take you to the old style pages.

This style moves the link to a more convenient place at the top of the page. The link is placed in the sidebar so this style may not work properly if you use another script to modify the appearance of the sidebar. See the "Script not working for me" discussion for a possible solution.

You may need to edit the url to suit your location/country.
