if you go to: http://www.cdrom.com/pub/png/pngsuite.html and check under the "Illegal and/or corrupted PNG images:" section you just see the alt text for the images. In Netscape 4.7 you get the broken images. Expected: You'll get the broken image icon and also the Alt text, properly as a tooltip when tooltips start working in Mozilla.
We're doing exactly wthat the HTML4 spec says should happen which is when an image can't berendered you render the alternate content instead. Navigator 4.x and IE have always done this incorrectly...
Ahh.. I wasn't aware that NS47 and IE was doing it wrong. Thanx...
We didn't know about it either until Ian Hickson brought it to our attention. But it's there in the HTML4 spec and Lynx has been doing it that way for years
Marking as verified won't fix per last comments.
