[R] using an image as a dendrogram label

[Rajarshi Guha]

Hi, does anybody know if it is possible to use an image (rather than  
text) to label the leaves of a dendrogram? I realize that this will  
not always lead to a useful on-screen display, but ideally I'd like  
to directly go from the dendrogram to a PDF and on-screen viewing is  
not to too important for me. Also, my trees are relatively small.

Any pointers would be apreciated
