What's that web page device called?...

Double_Faces

Ya know the one. It's where there are thumbnails on a side of the screen and then hovering over them makes the photo appear in full size on the other side of the page. What would that be called and how would I learn how to do it?

Vague much?

FatmanGames

Try this, or this, or this?

This might be closer, but didn't see a source code download link.

Jasconius

I don't know if he means like a pre-built tool.

What he is describing is a basic javascript image rollover gallery.

It requires basic javascript knowledge and a dash of DOM scripting.

But I'm sure the links that Fatman provided will get you where you need to go without actually having to learn that stuff.

Yeah, the links I gave give source code, are generally free, etc. So, if you and I think the same thing... well, he's set. if not, he needs to explain more.
