Replacing background procedure questions

[sallyanne]

If you want to remove a background. Make a selection around the area you want to keep, (I use paths to be more accurate, then paths to selection, but you can do it other ways) feather your selection so your edges are not quite so harsh arround your image. 3px for a small image up to 8px for a large image. Making sure you have an alpha channel. Then, invert your selection and delete/clear. You should now have a transparent background. Put a layer of your choice underneath and it will show through the transparent sections of your image.
There is a foreground select in gimp plus the free select tool. Masks and even a interactive one in GMIC-Qt
