There is an issue, when you plot larger images. Then the operation runs quite a while and the hard drive is used heavily. Probable cause: The array information is stored in memory and after a while the memory is swapped onto the hard disk. This slows down the operation.

Note: internally a SpatialGridDataFrame is created which creates a full grid (even if the array is sparse)
