Start with a high resolution image and use an image scaling interpolation that doesn't butcher the image.
for example here is the same image but with no interpolation.
photoshop, gimp or even paintdotnet have various options for scaling.
Finally for avatars make sure your final image is the correct size that it will be displayed, I think jsp will re-size it if it's not and it may come out blurry.
