I was wondering how you make your homepage a certain size?

I have a webpage that opens just fine but there is soo much white around it. Also, when a picture is clicked on to enlarge.. how do you make the window a smaller.. it opens to full size. Like when you open a link for a defination, it opens in a seperate smaller window.. how do you do that in Frontpage?

I make it a habit to try and not change people's window size. I find it horribly annoying when some site changes how I want my windows. Just design the site to either scale if it's a scalable design or center/left align it. If you want to get rid of the white, just make a background image, or add scaleable elements to fill the space. Popups are different, you can just use the window.open(link, name, properties); command to open a new window to a certain size. That's cool, just don't mess wit hthe main window size.
