Insert an image placeholder
An image placeholder is a graphic that you use until final artwork is ready
to be added to a web page. An image placeholder is useful when you lay out
web pages because it allows you to position an image on a page before you
actually create the image.
1. In the Document window, click once inside the first row of the
first table.
2.
Select Insert > Image Objects > Image Placeholder.
3.
In the Image Placeholder dialog box, do the following:
■
Type banner_graphic in the Name text box.
■
Enter 700 in the Width text box.
■
Enter 90 in the Height text box.
■
Click the color box and select a color from the color picker. For this
tutorial, select a reddish brown (#993300).
■
Leave the Alternate Text text box blank.

A note on alternative text Alternative text is a textual description of an image on a web page. It is part
of the HTML code and does not appear on the page. It’s important to provide alternative text for most of
your images so that people who use screen readers or text-only browsers can receive the information
provided by the image. In the case of a banner graphic, which merely displays a logo for a website, it is not
essential to provide alternative text. When you leave the Alternate Text text box blank in the Image
Placeholder dialog box, Dreamweaver adds an
alt=""
attribute to the
img
tag. Later, if you want to add
alternative text to an image, you can select the image and enter the alternative text in the Property
inspector. For example, if you later change the logo to include a phone number or address, you would
want to provide that information as alternative text.
