(Hope this is in the right section)...

I have a gorgeous candid snap of my neice that I want to remove the back ground from.

I have GIMP on this laptop and will use this to edit the photo if it is easy to do.

So is there anyone who may be able to give me a step by step run down on removing a background to have just a plain colour (black or white) background, it would be VERY much appreciated.

Thanks in advance.
