seoArt: sometimes there isn't. A concrete example - recently I had a design that called for antialiased rounded buttons that could sit on any of 12 different colours, with more in the pipeline. I would have had to make up 12 different styles of buttons (one for each styles). Alternatively I just made one 32-bit alpha PNG and it all worked fine.
