CSS sprites are great for minimizing the number of requests made for loading images, however, the design and coding part can be painful if there are too many images.

Spritemapper is a tool for easing this process by merging multiple images into a single one and creating the CSS positioning rules for each slice.

The tool is a simple command-line tool that performs the job via a Python package including its own PNG and CSS parser (without any 3rd-party dependencies).
