One of the commonly reported bugs on Connect is that Google Image Search shows grey boxes for some of the images in IE9 Beta. I had a quick look at the site this afternoon, and I can easily reproduce the problem, as you can see in the screenshot below.
Now, I tend to debug things first from the network level, so I fired up my trusty HTTP debugger and observed the traffic as I scrolled the page. I quickly noticed something interesting:
static function OnBeforeResponse(oSession: Session)
if (oSession.uriContains("jsonp") &&
(oSession.oResponse["Content-Type"] == "text/plain"))
I sent a mail over to the Google team and I’m confident that this will be fixed shortly.
Thanks for trying the IE9 beta and sending us your feedback!
