@the_treeOct 25.2006 — #Okay, you do realise that will be of no use to anyone right? I suspect porterhouse is confusing alt attributes (there is no such thing as an alt tag) with title attributes, a mistake inspired by IEs tooltip use of alt tags which is quite incorrect and misleading to begining developers.
@felgallOct 25.2006 — #The alt attribute is to supply alternate text for when an image can't be displayed. As there is no point in having alternate text to display when a piece of text can't display the alt attribute only applies to images. Internet Explorer contains a bug where if an image has alt text and no title text then the title attribute of the image is assumed to contain the same content as the alt attribute. The title attribute is used to display the contained text as a tooltip when the mouse hovers over the object that the title belongs to.
<img src="myimage.gif" alt="text to display if you can't see the image"
title="Text to display when the mouse moves over the image">
<span title="text to display when the mouse moves over the following text">hello</span>
You can fix the bug in IE by always supplying a title attribute in your images.
<img src="myimage.gif" alt="text to display if you can't see the image" title="">
