Good point, but while we're talking about solutions, I think it's time to 
recognize that specifying width and height in a style sheet (once for one 
image in a site) is easier and provides greater flexibility than including 
the width and height with each and every <IMG> tag.  While I almost always 
use the WIDTH and HEIGHT attributes myself, I would not want to see them 
REQUIRED since that would prevent the real solution (style sheets) from 
becoming a reality.

I haven't touched Spyglass Mosaic in a long time, but Opera handles ALT 
text very well when images are turned off.  It shows the text as it would 
show plain text, except that it adds a border around it (I guess to 
indicate to the user that an image is present--ideally this should be a 
user option).  Netscape 2.x isn't too bad; it ignores WIDTH and HEIGHT 
when image loading is off, and instead sizes the image frame based on the 
ALT text, but it still includes that ugly "THERE'S AN IMAGE HERE, STUPID!" 
icon.
