Hello dear community.
I'm trying to create extract colors from images fetched from Flickr. That all works really great to the point when I try to process that images in canvas with getImageData().
As described through WHATWG loading an image into canvas set a flag so you cannot maniplate that. So my question is does FLICKR support CORS?
<script type="text/javascript">
var img= new Image;
var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');
var src = "fetched-flickr-image-url";
img.crossOrigin = "Anonymous";
img.src = src;
img.onload = function() {
ctx.drawImage( img, 0, 0 );
var image_data = ctx.getImageData(0, 0, 100, 100);//Throw the Security error
}
});
</script>
I also tried to do the image processing in but thats a really heavy process (took about 4mins to process 250 images).
If you have any clues just ping me.

Not yet; see here for discussion.
They now appear to be sending CORS headers for images but with
Access-Control-Allow-Origin: http://www.flickr.com
, which isn't much help but at least they're sending the headers now.
