Do you have Photoshop? If not...look in your graphic app for an option called feather(ing). Select 1 or 2 or 3 pixels for your feathering and then pull the image off of the old background and place on the new background. The feathering softens the edges of your selection. http://www.techtutor.tv/photoshop-cs3/feather-an-image-in-photoshop-cs3.html
