I have a very important question...
I want to use the Twenty Ten Theme as basis for my new portal. But I want to customize the design to meet my needs. I want the whole theme to be 960 pixels wide and changed some settings in the style.css file. But I have a serious problem with the header image. When going to the Custom Header (under Appearances) in the admin menu, I see that the only option is to use 940 × 198 pixels images for my header. As mentioned above I have now changed the styles a little bit to prepare for a custom design, but how can I implement a header image of 960px (width) and 488px (height)if the only option I have is 940 × 198 pixels? I tried with the image I want to use but when the image appears it says that I must crop it to fit in. How can I override that?
Thank you in advance!
