I have a question about including your gallary into your mainsite.
Example: http://www.mugglenet.com/gallery/index.php
I'm sorry if this topic doesn't belong here and for my bad english. :-\
Create a Coppermine theme that matches the look of your site. Use the custom header and footer to include navigation elements if you want.
