Customizing phpAlbum

Hi there

Just installed phpAlbum - it's great! Thank you.

I'd just like to know how I can customize the templates. I'd like to be able to add google adsense to the pages that display the full sized photo

As well, I'd like to install java scripts that prevent right clicking to protect my images

Lastly - in the demo site, the different albums have a thumbnail photo. How do I add a thumbnail to my album in the navigation menu on the left hand side

Thanks so much for your help!
