Thanks for everything, guys.

Hey there, all. I just started using Paint.net, and while I love it, I am functionally useless with it as of now. I am making a pair of shoes on another website, and I need this image as a picture for the shoe, but no matter what I try, the image always saves as a white background, when all I want to save is the picture itself WITHOUT the white background. If anyone could help, I would really appreciate it. Thanks in advance.
