First! Sorry for my bad english, im a German and its my schoolenglish

On my Site, http://www.unser-kleiner-zoo.eu is the Mainsite not so optimal.
I have packed the Pictures in a Table, that locks terrible, what can i do?

I havve tried to pack the Pictures one below the other, but thats not so good

Too long and many Place betwenn the Widgets...

Have anyone an Idea?

Another Problem:
I would link the Header Pictures gladly to my Fotogalery, its http://unser-kleiner-zoo.eu/fotos/, but not to the Home of Wordpress?
What can i do?
