After some debate with Robert (who lives in Papua New Guinea) I decided to install different theme. The K2 theme is highly adaptable and has some nice features. Like a real-time search and a tool to scroll to older posts on the top of your screen. And for the most visual part I can add any picture instantly to the top (header) of the blog. You can find the archives on top now.
There are a lot more features, but I will not bore you with them.
