sliding door template help

Hey to all readers.
You know in the sliding door template, there’s a sliding effect menu on the top, with titles for each like ‘the zoo’ ‘people’ ‘nature’ with their pictures? If people don’t know what im talking about, you can visit my web site now to see; watchyourself.net
So, hoe can i change them ? Like, name them whatever i want, and add the pictures i want?

Please reply.

Thanks,
Vivee
