I don't know if this should go in CSS or HTML...

Anyway, is it possible to make a background image stretch itself to the maximum available screen in the browser, or at least make it adapt depending on the user's screen resolution?

Thanks,

Nope... you can't adjust a background image's size. You'll have to alter it using a graphics program.

Ah, I see. Well, thanks.

no problem ;)
