I wrote a blog post on thumbnails a while back. Some of the details may have changed since then, but you might see if it helps.

Basically, the thumbnail options are specified in a Spring Bean XML config file. That file is in /WEB-INF/classes/alfresco/thumbnail-service-context.xml.

You can override those beans by copying the file into /WEB-INF/classes/alfresco/extension/ and modifying as you see fit.

More info on overriding the config can be found on this wiki page.

Thanks
