RGB color images are not recognised as such after image export

[mirickmi]

Hi,

after image export, RGB images are not displayed as coloured images anymore.

Simple example:

img = read.image("C:/users/XXX/Desktop/rgbImg.tif", normalize = FALSE)
write.image(img, "rgbImg_2.tif")

This beautiful piece of art (left) becomes a three channel image where those are not recognised as Red, Green and Blue anymore (right).
