Plugin chnages NavBar

Hi there.

Great start for the plugin, but sadly I have a problem.
The plugin changes my NavBar, Nav links disappear and only 123 is showed to switch images.
I would prefer not to have a switcher on the pages at all, just a simple slideshow in the background.

Thank you.

Oh, and some options would be great like: Choose directory for images, change time for transitions etc.
