From the developer:
Spritecrafter is a utility that helps web developers and artists quickly assemble large numbers of sprite sheets (such as those used in CSS hovers) from individual state images. Spritecrafter can create two and three-state sprite images in both horizontal and vertical orientations. Any Preview-supported image format is supported for import and final sprite images can be exported in BMP, GIF, JPEG, and PNG formats.
