Background image in browser?

[pkng]

Hi!

I would like to put an image in the background that covers the hole screen, like this website: http://www.engelholm.se/ and then put a page in the center.

How is that done? Must the image have a greater resolution to look good in 24" and greater monitors? Or do they check the resolution with some script and then open an image that fit the visiters screen?

I am curious and want to find out! :) :confused:

Thanks!

It's the same image at the same resolution no matter what your window size... they just center it and you see more of it if you have a larger screen.

1981 width so it looks like they've designed it to look OK on up to a 24 inch (1920x1200) screen. Anything larger than that, it still wouldn't look too bad because they've faded it out.
