Always add an empty alt attribute to every spacer or decorative image you use in your website, i.e. <img src=”spacer.gif” alt=””>.
If spacer or decorative images have no alt attributes, those browsing with images off, or with text browsers, will either see or hear the file name, or the text ‘[image]’, for each image lacking an alt attribute.
