Ever wanted to run a single command in your website’s images directory and have every image losslessly optimized (compressed) in place? Now you can, with the smusher gem. I just ran it on our images dir and found an overall savings of 10%. If you’re not as rigorous as I am about saving images from Photoshop with good compression, the savings would be even greater!
