These can be used as textures for a variety of different 3D applications, Bryce or Vue for example, you can load them as texture images to apply to tree leaves, or apply them to particle leaves in 3DMax. or for smaller uses, you can convert the image to .bmp or .jpg and can trace the contour in say Rhino to create a leaf model that you can apply the texture back onto for single leaves(leaf floating on water, etc).
