Hi everyone,

I am new in using Zenphoto, my blog is at www.otaku-life.com and I have installed Zenphoto at www.otaku-life.com/gallery, May I know if zen photo can have the same theme as my blog? If yes, how do I change it?

Thanks

I think you can't do this out of the box.
I would recommend the article on http://tech.einaregilsson.com/2007/08/06/integrating-zenphoto-into-wordpress/ how to integrate zenphoto into Wordpress. Together with a bit code and css playing you can make zenphoto using the same design as wordpress.
Have fun

Basically two ways:
1. Make your own Zenphoto theme that looks like your blog theme: http://www.zenphoto.org/2008/05/theming-tutorial/
2. Use this method to include Zenphoto in your current site: http://www.zenphoto.org/2008/01/hacks/#zenphoto-as-plugin

In any case you will have to do some work adjusting some (X)HTML and CSS (and probably PHP) to match the look.
