Plugin Help for a Newbie

This is my first experience with WordPress. So far I am really impressed, but can’t figure out how to create links to the plugins that I have installed. For example, I have the NextGEN photo gallery installed, and a photo gallery setup, but can’t figure out how to create a link to it from my home page. I seem to be having this trouble with all of the plugins I have installed. I know that it is just something I haven’t figured out yet, so if anyone can help me out I would really appreciate it!

Thanks in advance!
