Wider images/content – theme twenty ten???

Hi! Thanks for reading:)

I started out with a childtheme of the 2010-theme, but I want my blog to have wider and larger photos. Then I probably need to widen the content page? Is this possible with a child-2010-theme, or is it better if I choose another theme with non-fixed with? Anybody?

I want my blogdesign, (I am starting a blog for showing art) to look somewhat like this:
