Edit: Launches the default image-editing program. Specify an image editor
in the File Types/Editors category of the Preferences dialog box. Choose
Edit?Preferences (Windows) or Dreamweaver?Preferences (Mac).

Optimize in Fireworks: Launches the Fireworks Optimization dialog
box. Check out Book III, Chapter 5 for more info about working with
Fireworks in conjunction with Dreamweaver.

Crop: Allows you to crop the graphic. Clicking this button opens an alert
dialog box that warns you about the permanence of any changes you
make. Click OK in the alert dialog box to continue. Cropping handles
then appear around the image that allow you to crop the image. Press
Enter (Windows) or Return (Mac) to accept the cropping.

Resample: Allows you to resample a resized image to improve the quality
of the image at the new size. This feature appears only after you
resize an image. Try, though, to keep resampling to a minimum (especially
resampling up) as this process can degrade the quality of the
image. If you really need a graphic at a different size, create a new
graphic in an image-editing program.

Brightness/Contrast: Allows you to adjust the brightness and contrast of
the image. Like the Crop tool, clicking the Brightness/Contrast button
opens an alert dialog box that warns you about the permanence of any
changes you make to the image. Click OK in the dialog box to continue
and a Brightness/Contrast dialog box appears. Move the sliders in the
dialog box to the left or the right to increase or decrease the brightness
