Build ID: 20150629114848

Steps to reproduce:

Created an img tag with attribute for cross origin. The Value can be set to anything. Like so: 

<img crossorigin="anonymous" src="...">


Actual results:

The image is not displayed. 


Expected results:

The image should have been displayed. I haven't seen this behaviour in any other tag but I haven't investigated it any further either.

Was the src attribute value same-origin with the original page?  Per spec, if @crossorigin is set and @src is not same-origin then the image will only be shown if the server responds with the proper CORS headers.

Since I am using a PHP proxy I have set the the header: 

header("Access-Control-Allow-Origin: *");

This works fine in Chrome and even IE.

That should work, as far as I can tell.  Do you have a testcase where it's not working that's public?

If not do you at least see any messages in the console about CORS blocking the load?
