What's much worse is they removed the precise and custom image size search. It's now impossible to search for a 32x32 icon or a 3200x1800 wallpaper. This dumbing down and feature removal is sad and silly.
You can add "imagesize:32x32" to your search query to only show images of a desired size, but I'd still rather see Google bring back the search tool option.
edit: Oh, it no longer has "custom" under the sizes. Hmm.
