This is so easy as to be untrue. One thing to remember is Gimp is a bitmap
editor and works in pixels, however

1. Your Hi Definition JPG might need cropping to the correct 6:9 aspect ratio

2. Use Image menu -> Scale Image then

2a. First set the horizontal and vertical resolution to 300 ppi

2b. Now set the image size to 1800 x 2700 pix (or 6 x 9 inches if pixels really
baffle you)

The whole thing can be done in a minute. Really dragging it out to 2 minute
