I’m interested in loading a picture in a canvas to read the pixel values. This requires the image to be CORS-enabled. Given an image URL, it is possible to know if the corresponding image is CORS-enabled without having to download it?

No code solution is http://www.corsproxy.com/ the other is the one mentioned above. Just make a short HEAD request with the method described here: HTTP HEAD Request in Javascript/Ajax? and check the responseHeaders.
