The browser already knows the name of the image.  Repeating this 
information in the ALT attribute is a waste of an otherwise good 
attribute.  It's also not nearly as useful as a textual description 
(TITLE) or textual replacement (ALT).  A decorative ornament should have 
empty ALT text, possibly with a descriptive TITLE.

Again, this is something that the browser should do for you if you're 
concerned about it.  But using ALT="wdglogo.gif (8 kB)" is harmful to the 
users most dependent on good ALT text--the search engines, the blind, and 
Lynx users.

ALT text should not indicate if an image is worth downloading; it should 
replace the image.  The TITLE attribute should be used to give the 
description you seek.
