How to save texture changes in UV image/editor?

I want to save this change and when I saved on my HD just as she gets originates

In your screenshot, the texture in the UV/Image editor seems to be the same as the original texture on the right of your screenshot (that you zoomed it), so i don’t understand why you expect it to be changed ?

The texture is “Tiled” on the plane because you have your UV coordinates scaled up in the Image editor. If you want the texture tiled, the best way to do it is in Gimp or Photoshop.
