Each image you add to your Web page increases the file size of the page and the download time. It's important to optimize your images, which means decreasing the file size. If you have Fireworks installed, you can optimize an image from Dreamweaver using Fireworks.

To optimize an image in Fireworks:

1	Select an image, then choose Commands > Optimize Image in Fireworks
2	Click No if a dialog box appears asking if you would like to use an existing Fireworks document as the source.
3	In the Optimize Images dialog box, you can adjust the settings under the Options tab on the left. After each adjustment, check the file size and download time that appears above the Preview pane.
	Tip: The best setting to adjust is Palette. Try setting it to Adaptive, then reduce the number of colors. Reduce the colors with the pull-down menu beneath and to the left of the Palette menu. Try different color settings and see how each setting affects the image preview. Choose the lowest setting you can before the image starts to lose quality.
4	Click Update when you are done.
