The HTML specification implies that this text should be shown to users "who have configured their graphical user agents not to display images" <http://www.w3.org/TR/REC-html40/struct/objects.html#h-13.8>. Firefox and Opera do this; WebKit should do so too. It's a useful feature for limiting bandwidth requirements. Personally I found it very useful when browsing Ubuntu's Launchpad over dialup and though HTTPS. I have reproduced this bug in svn r31157 on linux, both Qt and Gtk ports. The bug is in core code, not platform specific. This is a longstanding bug from KHTML which has yet to be fixed in WebKit. Also at Kubuntu Launchpad <https://bugs.launchpad.net/bugs/136348>. Also at KDE bugzilla <http://bugs.kde.org/show_bug.cgi?id=145224>. 74519 1 19897 alan-jenkins 2008-03-20 07:07:56 -0700 Created attachment 19897 Test case Here's an example of an image with ALT text. Note that if you try this in Firefox you need to access it via http. If you use file:// then the image will load even if you disable image loading. 74520 2 19898 alan-jenkins 2008-03-20 07:20:30 -0700 Created attachment 19898 Proposed fix Regression tests aren't running under linux :-(. I've tried to follow the rest of the code submission guidelines though. Build and run-tested, on linux Qt and Gtk. Does more or less what it's supposed to. It's not ideal - Firefox has a better solution, where it almost looks like the ALT text is made into a text node and completely replaces the image. In particular, the ALT text for inline images will not have the same baseline as the surrounding text. It's much better than doing nothing though. 78618 3 19898 hyatt 2008-04-22 22:39:01 -0700 Comment on attachment 19898 Proposed fix You didn't mean to turn off image autoloading in the QTLauncher did you? This patch will need to be updated to reflect the changes that made generated content wrap the cached image... you might need a virtual stillNeedsLoad method on RenderImage (similar to errorOccurred).
