Keep plugins from adding code to every page?

I’m wondering how to keep plugins from adding their code to every page.

For instance I have a plugin for a slideshow that I use on only one page of my website. But it adds it’s scripts to every page. Is there a way to allow it to only put it’s script on a page that includes it’s call?

I feel like I read this somewhere but can’t seem to find it now.

Thanks in advance!
