There are times when it may be desirable to replace the sky with another one which is visually more appealing. Perhaps the sky is blown and appears white or it is just plain dreary!
You could use the technique that I described in the article about Removing Image Backgrounds which uses the quick mask. You would of course need to go one step further than described in that article. You would need to add another layer (ctrl + L - will open the layers dialog box) below the main picture and paste the new sky into this layer. It will be visible on all the transparent parts of the image.
With the example images below I used a different but equally effective technique to achieve the required result.

The assumption is that you have a basic understanding of how to use the gimp.
