remove bullet point???

Hi, this plugin is great and allows me to add photo galleries easy to any page or post, however when i view the page that contains the gallery, there is a bullet point between each image.

This is probably something to do with the li tag. I have tried editing the CSS file that comes with the plugin, but cannot seem to remove the bullet point.

Has anyone has the same problem? Can anyone suggest a fix for this?
