I installed Theme Switcher plugin for WordPress, making it possible to change the WordPress theme by clicking the option in the sidebar.
To complement the availability of switching WP themes in my blog, I added corresponding Coppermine themes designed to match WP themes. There was no existing Coppermine theme for my WordPress theme, Ocadia, so I worked on it for much of the day. I’m on vacation.
I tweaked the code of the blog and gallery themes so that when switching between the two applications, the theme would be preserved.
