For some reason firefox is not rendering an image element on my simple page. This is very unexpected for me. It's a simple html file so maybe you guys could have a look at it.
Sometimes it does work for me. When it doesn't it displays the alt attribute. It seems to only work when I first load the page or click the go button for my address bar.
Hmm... I don't have a slow connection and even then why would the connection effect the rendering, that is the alt attribute thing.
Don't know what to tell you. I can view it absolutely perfectly. Like Kieran, I refreshed multiple times, also returned to the site by clicking your link several times. Maybe you have something wrong with your FF installation? Are you saying that you see the Tooltip that displays the Alt attribute sometimes? Not while you're hovering over the image?
