As you can see, qtwebkit show a broken img instead of alternative text
Original bug report:
Changing the component to images. It seems this is not Qt specific, Safari with the trunk of WebKit has the same behavior.
Furthermore, if the AutoLoadImages setting is turned off, nothing at all is displayed - I would expect to see the alt text in this case.
I have reproduced this on latest trunk on linux, and believe I have a good idea of what is going wrong. will pursue a fix.
