Thanks so much for the quick reply. I created the new theme by making a copy of the aero folder and aero.theme.
I renamed the new aero folder to "groovy" and the new aero.theme to groovy.theme.
Inside the new groovy folder. I renamed aero.msstyles to groovy.msstyles
In en-GB and en-US, I renamed aero.msstyles.mui to groovy.msstyles.mui
I edited groovy.theme and replaced DisplayName=aero to DisplayName=groovy
and Path=%ResourceDir%\Themes\groovy\groovy.msstyles
When I edited the theme, I used the standard aero theme, then rebooted. When I look in resource hacker at the the groovy.msstyles file it shows my new image. I uploaded a screenshot
