Figure 19: Select Image Source Dialog Box

6. Since we set the preferences earlier to remind us to abide by web accessibility rules, the

Image Tag Accessibility Attributes dialog box will appear (Figure 20). Where it says

Alternate Text:, type “Homer Simpson”. This will allow the screen reader to skip the

image and continue reading the page while it allows the user to know there was an

image of Homer Simpson in that location on the web page.

Figure 20: Image Tag Accessibility Attributes Dialog Box

Note: If the image you inserted was primarily for page design (e.g., a header or footer image)

and not important for a screen reader to read to a blind or visually-impaired user, you would

ignore the Alternate Text: text box and simply click the OK button. Then later in the

Properties Inspector, you should select the pop-up menu next to Alt and select <empty>. This

will place quotation marks next to the Alt tag in the code (e.g., alt=””), which will not be read by

the screen reader. When you run a Dreamweaver Accessibility Report on a Cal Poly template

(discussed later on in this tutorial) you will find many empty Alt tags, which have been done this

way so that they are ignored by a screen reader.
