We have used Github for coding ideas and we now it’s our turn to share our insight. 

Github is a stable respository with millions of opensource and private projects. It’s also a place full of talented developers around the world. 

Being "talented" developers, we have launched our first library to Github in MIT license. Using this library, you can turn images to grayscale easily with javascript and css. 

Want to improve photo elegancy with grayscale? Try our free library image-grayscale at Github.
