Using だ as a Verb


I was reading through the following
[blog](http://nihonshock.com/2010/02/particles-the-difference-between-wa-and-
ga/) and came across a particularly interesting example on the use of は and が.

The author explains that in the context of a young man pointing at a number of
pictures of girls he could use the following sentence to say "I like her".

> 私は彼女だね。

I am reading this as the following:

私は - As for me 彼女だね - she it is right?

I know that the adjective for "like" is 好き however the author also describes だ
as the Verb for "being" I can't find this Verb anywhere online, and as far as
I know だ is just the informal equivalent of the polite です.

Can someone help explain this to me? I'm guessing the answer is very much
related to the context so relies heavily on the question, probably something
like "which one do you like?"
