Ah, I see, ?addlogo is much easier than grid in this case, as one sees 
in a (slightly modified) version of the help example:

x <- read.pnm(system.file("pictures/logo.ppm", package="pixmap")[1])
plot(sample(1:100))
for (i in 1:7)
   addlogo(x, px=c(0, (101/77)*11), py=c((i-1)*11, i*11), asp=1)


Thank you
