Fireworks

Adobe Fireworks is a commercial raster and vector graphics editor hybrid from Adobe that’s available for the Mac and Windows operating systems. Designed specifically for web designers (unlike Photoshop), Fireworks brings you a plethora of tools and options that make full web layout prototyping a breeze. Among its notable features are: "slices" for slicing and dicing a design mockup into HTML/CSS for rapidly creating prototypes (though you should avoid using auto-generated source code for the end-build), the ability to package an entire site design as a PDF with clickable components for interactive and impressive site prototypes, and optimization tools for making your web graphics as lightweight as possible.
