Use your favorite image editor (even Paint works) to crop the faces you want to make into a morph animation. FaceMorpher Lite automatically detects the control points (eyebrows, eyelids, mouth, nose, etc.) and draws them over the face.
If you're not pleased with the final result, you can correct the control points manually and place them whenever you think best. The result can be exported in different formats, including GIF, AVI, and SWF.
