Blogger vs WordPress Blog

I am creating identical looking blog pages, one will be in German, one in English. I need them to look identical/similar which means using the exact same images. How do I access my media library that I created when making the first site while working on my second one? All I get is that my media library is empty - which it isn't when I look at the first blog site. Any ideas welcome - and please keep it simple as I am not a tekkie... :)

The blog I need help with is ulrikeascher.wordpress.com.
