Because either someone else or you have changed the image size in camera. All digital cameras have at least 3 image sizes depending on resolution. Now I don't know much but I know the max resolution size it 4,608 x 3,456 pixels in your camera, Canon A2400. Now its on smallest image size, im sure. Check the camera settings you can change it from there.
