Hello there, I was just wondering if Zenphoto can be integrated into a certain webpage? Sorry if this is too vague, I am pretty new to web design.

That is indeed a little vague. It can in several ways. One way is to adjust or make a theme to look like the site.
If you are really new to web design, I recommend that you get some knowledge about (X)HTML, CSS (and a little PHP maybe) before trying that.
