When selecting a theme you should think more about its flexibility than the nice pictures or layout. The picture/header can be changed anytime. You can even take the pictures from other themes. They are usually stored in wp-content/themes/THEMENAME/images/(header).
A very flexible WordPress Theme is named ATAHUALPA . Simply search for it in your WP blog: “Appearance; Add New Themes;Search” and than click on the “install” link. You can see the basic theme in my new web http://product-reviews-group.info. I still have to change the header image and tweak some parameters like font size and colors, but all this can be done later. Changing the look and feel is very easy by setting the parameters. The main advantage of this theme is that you can use it over and over again for other blogs. Once you get to know it you will love it. If not, simply change back to your other theme.
!Another advantage of ATAHUALPA is that you can share experiences with other users you know and even get support. 
If you like it, remember to donate a few bucks to the creator.
