Open Source image editor that handles PNG Alpha transparency correctly?

Question

I want to be able to take a sample image, and be able to fade out the background.

For example, I might take a picture of a bird. Make most of the background almost completely transparent, and have a smooth transition to full opacity adjacent to the subject.

Most of all, I want to be able to save / export to PNG.

GIMP should be able to do what you want. It's free and open source.

Paint.NET if you're on Windows. IMO, a lot easier to deal with than The GIMP, if you're already slightly familiar with Photoshop.

Gimp is a great application. However, the learning curve is pretty steep. I have not figured out how to do a simple color replacement or transparency with it yet. The easiest program I have ever used for that is Paint Shop Pro.

After reading about Paint.Net I downloaded it. It beat Gimp Hands Down. A great program for the Novice.
