Change font and load image

["Johnny" <johnny troppoilmigliore inwind it>]

Hi, I'm using gtk1.2 and I've tried to change the font size with
Style->font_name="Sans 14";
where Style is a GtkRcStyle, but it doesn't change.

I don't remember if I had asked it yet:  how can I load an image in my interface?

sorry for my bad English
Thanks
Johnny
