Hey people!

I've started creating a website on Photoshop CS4.
I'm almost finished, but have only NOW noticed that at the start of this project, when I went to File > New, I create a 1100 by 1100 px document: Too big for what I want it for.

My question is: Do any of you know if I can transfer my whole websites (I.e. All the layers/text etc) to another smaller document?

Thanks a lot.
