investgate mechanism to detect images off in IE

[Becky Gibson]

Currently images turned off in the browser is only detected in Firefox. Need to investigate how to test for this in IE without requiring synchronous load of an image.

[Becky Gibson]

moving to 1.1 - not ideal because we currently don't detect images off in IE but we are covered for 1.0 because we DO detect images off in Firefox

Becky - obviously our high-contrast mode works in IE. Are you talking about for when it isn't high contrast mode, but images are still turned off?

[Becky Gibson]

Correct. I never found a way to detect JUST images off in IE.

I googled this and didn't find anything other than loading an image synchronously:

​http://groups.google.com/group/jquery-en/browse_thread/thread/4480f62e57bd7e82?pli=1

var test = new Image(); 
test.onload = myOnLoadFunc;
test.src = 'test.gif#'+(new Date()).getTime()

Then you run into questions of timeouts... how long do you want for myOnLoadFunc() to get called?

So, I'll will mark this as "patchwelcome" to indicate that we would fix it if we knew how to do it more elegantly.
