I than clicked on optimized and reduced the image size.
This shows that the file size has been reduced in the second image.
scenario 2
I found a picture that was 2400x1200 on google images
I saved that picture and opened it in gimp
Than i right clicked the image and selected the canvas size
On this second window, I reduced the height and the width of the canvas size.
When I applied the changes to the canvas size, this was the new size of the canvas.
