Sorry Eddie, but this is not correct.

The alt attribute is used for the visually impaired. The moment the image is loaded, their screen reader says what's in the alt tag. It's necessary to add this to be ok with xhtml webdesign. But it's not meant to appear as a text hanging on your cursor when you mouse over the image. For that purpose you need the title attribute.

Correct browsers like Firefox do not show a text you typed for alt. Internet Exlorer does show the info but that is not because it's correct, but because it's Microsoft who, once again, try to impose their personal vision on the Internet.

src=""  id (or class)="" alt="" title="" width="" height=""

are the normal attributes of the img tag in up-to-date webdesign.

There are no Borg. All resistance is fertile.
