Dear Chuanwen You could write a new function around identify() that looks for the observation ID, looks up the corresponding picture and plots it. None of the spatial packages will do this automagically.

I searched CRAN task View, it seems this is the only place. The data we are working on is multivariate data, where each observation has p features(variables). For each observation, all features are computed/subtract from a picture, i.e., one observation correspondents to one picture, which is then summarized by a p-dimension vector( features). Now in a x-y plot of two features ( variables), we want to click or select some observations, could it possible to bring up the correspondent pictures of those observations ? In R, I know identify() function. But here we want to bring up the pictures. Any package can do this ? Thank you very much for your time!
