Vector images are made of mathematical formulas. When enlarged, the mathematical formula is simply multiplied, thus the quality remains perfectly crisp.
A typical photo image (BMP) is made of pixels that are like little squares. When a BMP isenlarged, the original pixel shapes remain and the final product is a photo composed of large squares.
Flash has a neat tool called vector trace that allows you to create a vector image out of a standard BMP image. The only real drawback is that these formulas can become very complex when lots of colors are used. So keep it simple and you’ll get something like this:
original
vector
Now the vector image looks a little funny because I had to scale down the colors to make it less complex. But the benefit of a vector image is that I could make this image the size of the moon and it would lose ZERO resolution. In other words, it would look exactly as it does now rather than have a bunch of little squares.
