Trying to find large image package to download

What I am looking for is a download file containing hundreds if not thousands of images. I need the images to be in the range of 1x1 to 10x10 pixels (or close) and each image to be a random color.

So Pretty much a photo cut into thousands of pixels (smaller images). I'm sure there is something out there like this but I've tried searching for something but I'm not having any luck.

Thanks if you can help!
