Spriting made easy
Background images make pages look good, but also make them slower. Each background image is an extra HTTP request. There's a fix: combine background images into a CSS sprite. But creating sprites is hard, requiring arcane knowledge and lots of trial and error. SpriteMe removes the hassles with the click of a button.
