It's really hard to change the size of the results without clicking on the "view web results" link.

Weird, I get no pics for this search, and no "view all web results..." for other searches...

Philipp, these steps can get you the "view all web results..." link:

1.search something in Google Images search first.
2.click on the "Web" label(above the search bar) directly, switch to web search results.
3.then switch back by clicking on the "Images" label
4,done.
