Google Image search recently added a new feature to search images up to 70 Mega pixel of images.

For instance if you like to search 4 Mega pixel of  desktop wallpaper, just select 4 Mega Pixel size in Larger option as shown below picture.

Using larger than option in Google image search you can search from 400×300 to 9600×7200 (70 Mega Pixel). Now it’s easy to search high quality images in Google image search with different pixels and sizes.
