Hi,

You could try the RGtk2 package using the GtkImage widget.

Like this:

library(RGtk2)
win <- gtkWindow()
image <- gtkImage(filename="foo.jpg")
win$add(image)

Should be fast...

if you need to draw R graphics on top of the image, you'd need to do
something a bit different and more complicated (draw R graphics to a pixmap
using cairoDevice and then superimpose the pixmap onto the image in the
expose handler for a GtkDrawingArea).

Hope this helps,
Michael
