JPEG files saved in grayscale mode (yes, JPEG has a luminance mode that is different from RGB mode) are 1.5 times smaller than in full color. This allows to provide higher resolution images in the same bandwidth. The economics are the problem. You can't store unlimited images for free. Big corporations have their own data centers, so they can afford it. I really think people will use it if it's absolutely free. But once you ask people to pay for storing their pictures things change.
