In addition to the other responses, you may want to look at the subplot function in the TeachingDemos package for a way to place the image at a location within the plot (the other answers so far use the image as a full background), see the last example on the help page for a way to use the R logo as a plotting symbol.
If you want to define your own symbols for plotting, look at the my.symbols function in the TeachingDemos package. Hope this helps, -- Gregory (Greg) L.
