 Nice, but if the require() fails and the package installs via
install.packages, you still have to do the require() (or 'library()'),
so you need something like:

  if(!require(rimage)){ install.packages("rimage") ; require(rimage) }

maybe we need a requireOrGet() function that goes and gets it from
CRAN if it can't find it :)
