Chapter 5. Working with Images > Page Loading Properties

Page Loading Properties

Not everyone who surfs the Web does so with image capabilities. Some users who have graphical browsers turn off image auto-loading, whereas others browse with a text-only browser. Visually impaired users may use text-to-speech browsers that read the page to them; and finally, mobile users may access the Web on a tiny, text-only screen, or by having their phone service read the page aloud. The only way these users will know the content of your images is if you provide a text alternative, often called an Alt tag (even though it's just an attribute of the img tag).

To add Alt text to an image tag

Select the image for which you want to provide an Alt text description.

In the Property inspector, type a description in the Alt text box (Figure 5.33).

Figure 5.33. Type the alternate text description in the Alt text box.

Press Enter (Return).

Users who view your page without image-viewing capability will be able to read the text description to find out whether they want to view or download the image (Figure 5.34).

Figure 5.34. In the browser window at the left, IE has auto-image loading turned off, or the image hasn't loaded properly. Instead of seeing only the broken image icon, the user is presented with the text description, and can decide whether to load the image. At the right are two windows from Lynx, the most popular text-only browser. The upper window shows the page without any Alt text—all you see is [INLINE] to indicate an image. The other Lynx window displays the Alt text.
