how to enlarge the logo

I would like to keep the logo image in the same position,
enalrging a bit its dimensions.
To do so, I suppose it is necessay to modify also the css style file, but modifying the dimension of the "gklogo.css" I obtain a bad results since the image is dropped by the style table.
Someone may help me?
thank you in advance
