If a graphic??™s dimensions are
increased, pixels are formulaically added; make the image small and pixels are removed according to a similar
algorithm. Dreamweaver includes a resampling option, which becomes available when an image is
resized, either by dragging the sizing handles or changing the values in the Width and Height fields of the
Property inspector.
Resampling in Dreamweaver is a one-click affair??”no parameters are set. Just choose the resized image and
click the Resample button on the Property inspector. As with the other built-in tools, an alert informs you
that the graphics file is being changed (unless you??™ve selected the Don??™t Show Me This Message Again
option).

Inserting Images 9
How the image resamples really depends on the image itself and the difference between the original image
size and the new size. Sometimes, resampling in either direction results in satisfactory images (see Figure
9-8). Typically, I find that small differences work far better than large ones; if you??™re making a major change
in image size, it??™s often better to use a dedicated graphics editor such as Fireworks or Photoshop.
FIGURE 9-8
These three images demonstrate how an image can be resampled after it has been reduced or increased in size.
