Website is loading very slow

Hey guys,
Wanted to ask if you know how to speed up the loading of my site? It's very image heavy and it takes almost a minute before anything shows up. And advice what to do without changing look? http://maxsiedentopf.com/
Thanks!

Do you have the caching plugin installed and running as recommended in the documentation?
