changing the header of the theme with your own design on K2

Hello,

I was wondering how we can change the header of a theme with the one we designed on photoshop. I simply want to create my own (jpeg) buttons on the header (i designed on photoshop). That’s all i want. I spent days to learn that but am now desperate =(.

I cannot integrate my PSd design with the current K2 theme’s header.
Is there any way to do it?
