[Gimp-user] Converting an image from square to round question

[Huntleybill <forums gimpusers com>]

I have attached an image of a dog I would like to use for a project. The picture
is square and I wanted it to be round. I used the tools in Gimp 2 to get the
round shape I need but there is still the white square visible.

When I paste this image into my project, it shows the white square background. I
need to get rid of the white square background and keep the circle and
everything in it.

How do I make that happen?
Thank you in advance for your help
Bill
