Konqueror doesn't display the alt information of image tags in web pages with autoloading of images turned off. This makes navigation on many sites difficult (sometimes impossible) that use linked images for navigation. Without the images being displayed, the alt text would be necessary to find the links, but with the current behaviour of Konqueror they are invisible. I had the same problem on Woody using KDE 3.2 backports, I don't remember about KDE 3.1.
