"Ever had Grandma Edna email you her latest vacation cruise photos, only to find the images so small and pixelated that she and Gramps look like they were made of LEGOs? VectorMagic has the answer. A free website from the folks down at Stanford, VectorMagic takes your raster images and turns them into smooth vector drawings. Unlike raster images, vector drawings are made of geometric shapes instead of pixels, so you can infinitely resize them with no fuzzy or blockiness! This makes them ideal for blowing up a small photo to, say, the size of your bedroom wall. Other programs that will do this, but VectorMagic is web-based and will run on most computers. Plus, its algorithms do an impressive job of translating photographs into realistic vectors — something others choke on."Sweet tech. I would totally recommend looking at the 2 minute video on how to use this site -
here. If you are wondering why you would want to use this, I remember using vector based images especially to create posters and/or large signs. It really makes a difference in the quality of the edges in your pictures.
