I`d like to announce the release of a new Eclipse Plugin called "Smartsprites". Install the plugin via our public updatesite. The plugin acts as a frontend to the SmartSprites CSS Sprite Generator. After installation the plugin will contribute the context menu "External Tools > Generate Spritemap" to the .css files in your workspace projects. As the plugin name implies it can be used to generate CSS Spritemap files.
The sources are available from the github repository.
