Subject: How to delete background using fuzzy select tool

 

I have selected the whole background which is all shaded leaving a neat
picture of the subject.

I am however not able to do anything with the selected area , not cut , not
insert a white plain colour.

An alfa channel was added.

I am a beginner with gimp and would be grateful if someone could advise what
I am doing wrong. 

 

There is the screenshot of my pic after selecting the backround.
