VectorMagic might be a pretty handy tool to add to your bag of tricks. I know there have been times when I’ve wished I could enlarge a non-vector image but couldn’t without it becoming so pixelated it was no longer useful. If you don’t know why a vector image is different; they can be enlarged without the distortion that occurs with standard .jpg and .gif formats.
If their claims are true then this could be very helpful. What do you think?
