Adjust the crop handles until the bounding box surrounds the area of the image that you want to keep.
3
Double-click inside the bounding box or press Enter to crop the selection.
4
A dialog box informs you that the image file you are cropping will be changed on disk. Click OK. Every pixel in the
selected bitmap outside the bounding box is removed, but other objects in the image remain.
5
Preview the image and ensure that it meets your expectations. If not, select Edit > Undo Crop to revert to the original
image.
Note: You can undo the effect of the Crop command (and revert to the original image file) up until the time that you
quit Dreamweaver, or edit the file in an external image-editing application.
Optimize an image
You can optimize images in your web pages from within Dreamweaver.
1
Open the page containing the image you want to optimize, select the image, and do either of the following:
• Click the Edit Image Settings button
in the image Property inspector.
• Select Modify > Image > Optimize.
2
Make your edits in the Image Optimization dialog box and click OK.
Sharpen an image
Sharpening increases the contrast of pixels around the edges of objects to increase the image’s definition or sharpness.
1
Open the page containing the image you want to sharpen, select the image, and do either of the following:
• Click the Sharpen button
in the image Property inspector.
• Select Modify > Image > Sharpen.
2
You can specify the degree of sharpening Dreamweaver applies to the image by dragging the slider control, or
entering a value between 0 and 10 in the text box. As you adjust the sharpness of the image using the Sharpness
dialog box, you can preview the change to the image.
3
Click OK when you are satisfied with the image.
4
Save your changes by selecting File > Save, or revert to the original image by selecting Edit > Undo Sharpen.
Note: You can only undo the effect of the Sharpen command (and revert to the original image file) prior to saving the
page containing the image. After you save the page, the changes made to the image are permanently saved.
Adjust the brightness and contrast of an image
Brightness/Contrast modifies the contrast or brightness of pixels in an image. This affects the highlights, shadows, and
midtones of an image. You typically use Brightness/Contrast when correcting images that are too dark or too light.

• Click the Brightness/Contrast
button in the image Property inspector.
• Select Modify > Image > Brightness/Contrast.
2
Drag the Brightness and Contrast sliders to adjust the settings. Values range from -100 to 100.

Click OK.
