Thanks SSwift I managed to find the same filter in GIMP and all I had to do was smudge the artifact a little and it looked nice and seamless, I forgot to scale up the image but Im sure after I do it again it will look fine,
thats a lot of work I managed to avoid getting 6 images for a skybox or 2 domes phew!
