OK,

I recently downloaded a webpage .psd template.
Opened it up in photoshop and made my modifications.

Then I saved it to get the html and slices.

I opened the html page in dreamweaver to make further changes.

The probleme the page always displays in the upper right corner of the browswer. It doesn't fill the screen or even centre nicely.

What am I doing wrong or what should I do?
