The grImport package on CRAN offers this functionality.  Although I would
caution that if you do this- consider carefully if adding the picture of
bacteria enhances or distracts from the results or analysis you are
presenting in the plot.

If the picture is not strongly related to the data you are presentin, and I
mean more related than just being a picture of the critter you analyzed, it
may be better to just leave it out.  Including it could lower the
signal-to-noise ratio of the graph and decrease the impact of the analysis.

I know it's a tough choice to omit a really good graphic when you have a
space constraint, but it is usually not worth sacrificing the clarity of
other graphics by smashing two things together if they are only marginally

Good luck!
