In
Dreamweaver, you can enter this alternative text in the Alt text box of the Image Property inspector.
If the![]()
tag does not contain an alt attribute, some screen readers read the filename
when they encounter the image, which slows down how quickly visually impaired users can
get to the real information on your page. For images that are purely visual and don??™t contribute to the meaning
of your content, such as bullets or spacer images, include a blank alt attribute. To do this, open the
Image Property inspector and select from the Alt drop-down list.
Currently, the alt attribute is the most valuable tool you have for providing a textual description of your
images. However, some images are just too complicated to describe in a few words and are too important to
gloss over. For these situations, the latest HTML specification includes the longdesc attribute. Although
none of the major browsers currently support this attribute, Dreamweaver is anticipating the future by
enabling you to specify a longdesc for your images.
In Dreamweaver, choose Edit ??? Preferences (Dreamweaver ??? Preferences), and, in the Accessibility category,
select the Images checkbox. When you add a new image to your page, the Image Tag Accessibility
Attributes dialog box appears, as shown in Figure 9-13.
