No, alt provides a replacement for the image, not a description. Using
a description leads to delightful webpages like
http://www.btplc.com/age_disability/ (picked on becuase it was the
first bad example I could find) which has:

  BT Logo - link to bt.com

* Does it really matter that its a logo?

* It has an <a> around it, the browser knows its a link and can tell
the user.

* Where else is something labeled "BT" likely to link? And if there is
somewhere, then why not include that information for people who can
see the image?
