question about changing width

[sartake]

I have a website 'www.takeshionline.com' and it's set to width 1024px, but when I try to get the header and menu to show on my gallery page they shrink to a smaller size even tho I have made it to 1024px in the HTML part. I tried changing in the config panel but it tells me the size is incorrect. How do I get it to show the header/menu in the correct size?
Would it be the padding/margins I need to change?
Thanx......

What exactly doesn't show as you expect? IMHO everything looks fine.

if you look at the main page image and menu then go to the gallery, you can see they shrink.

They're looking exactly the same for me (tested with Firefox 10).

Hmmmmm. 
That's weird. I'm using firefox 10 also so I wonder why it shows different for me...Oh well...
