Create Starts Fireworks to create a replacement image. The Create button is disabled unless Fireworks is also
installed on your computer.
Update from original When the web image (that is, the image on the Dreamweaver page) is out of sync with the
original Photoshop file, Dreamweaver detects that the original file has been updated, and displays one of the Smart
Object icon’s arrows in red. When you select the web image in Design view and click the Update from Original
button in the Property inspector, the image updates automatically, reflecting any changes that you made to the
original Photoshop file.
Color Specifies a color for the image placeholder.
Edit images in Dreamweaver
You can resample, crop, optimize, and sharpen images in Dreamweaver. You can also adjust their brightness and
contrast.
Image-editing features
Dreamweaver provides basic image-editing features that let you modify images without having to use an external
image-editing application such as Fireworks or Photoshop. The Dreamweaver image-editing tools are designed to let
you easily work with content designers responsible for creating image files for use on your website.
Note: You do not need to have Fireworks or other image-editing applications installed on your computer to use the
Dreamweaver image-editing features.

Select Modify > Image. Set any of these Dreamweaver image-editing features:
Resample Adds or subtracts pixels from a resized JPEG and GIF image files to match the appearance of the original
image as closely as possible. Resampling an image reduces its file size and improves download performance.
When you resize an image in Dreamweaver, you can resample it to accommodate its new dimensions. When a
bitmap object is resampled, pixels are added to or removed from the image to make it larger or smaller. Resampling
an image to a higher resolution typically causes little loss of quality. Resampling to a lower resolution, however,
always causes data loss and usually a drop in quality.
Crop Edit images by reducing the area of the image. Typically, you’ll want to crop an image to place more emphasis
on the subject of the image, and remove unwanted aspects surrounding the center of interest in the image.
Brightness and 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.
Sharpen Adjusts the focus of an image by increasing the contrast of edges found within the image. When you scan
an image, or take a digital photo, the default action of most image capturing software is to soften the edges of objects
in the image. This prevents extremely fine details from becoming lost in the pixels from which digital images are
composed. However, to bring out the details in digital image files, it is often necessary to sharpen the image, thereby
increasing edge contrast, and making the image appear sharper.
Note: Dreamweaver image-editing features apply only to JPEG, GIF, and PNG image file formats. Other bitmap image
file formats cannot be edited using these image-editing features.
Crop an image
Dreamweaver lets you crop (or trim) bitmap file images.
