Since you received a PSD file and you want to turn it into a webpage, here is what you do, in a nutshell...

1) Open the PSD document in Photoshop and edit it the way you want.

2) Once you are done, and this is important...use the SPLICE TOOL to break up the PSD document into images...each splice will be a jpg file that you would save.

3) Go to File--Save for Web and you'll see your splices pieced together.

4) Select JPG HIGH for your resolution so that your images don't appear all blocky and pixel-like...

5) Save the PSD file as a .html file (i.e. index.html, whatever.html, etc.)

6) Next, open Dreamweaver, or your favorite HTML editor. Go to File--Open to open the PSD document...

7) Center the document...

8) If you need to add meta tags or keywords for SEO purposes, do so in the document.
