Nofollow for images

Hi. I’m using WordPress 2.9 with Mystique theme. The problem is that WP automatically generates pages for images in post (for example for picture in http://gadgetfreaks.ru/2010/01/19/htc-nexus-one-problemy-prodolzhayutsya/ it generated the following page: http://gadgetfreaks.ru/2010/01/19/htc-nexus-one-problemy-prodolzhayutsya/nexusone2/). Search engines index pages like this and show them among other search result, but these pages are absolutely useless and irrelevant, there is even no text there. How to add noindex instruction to this type of pages (or how to add nofollow to all pictures in original post)?
