folder icon to browse to a document on your site, or manually type the URL.
Alt Specifies alternative text that appears in place of the image for text-only browsers or for browsers that have been
set to download images manually. For visually impaired users who use speech synthesizers with text-only browsers,
the text is spoken out loud. In some browsers, this text also appears when the pointer is over the image.

on your computer.

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.
