canvas.toDataURL() SecurityError

Unless google serves this image with the correct Access-Control-Allow-Origin header, then you wont be able to use their image in canvas. This is due to not having CORS approval. You can read more about this here, but it essentially means:

Although you can use images without CORS approval in your canvas, doing so taints the canvas. Once a canvas has been tainted, you can no longer pull data back out of the canvas. For example, you can no longer use the canvas toBlob(), toDataURL(), or getImageData() methods; doing so will throw a security error.

This protects users from having private data exposed by using images to pull information from remote web sites without permission.

I suggest just passing the URL to your server-side language and using curl to download the image. Be careful to sanitise this though!

EDIT:

As this answer is still the accepted answer, you should check out @shadyshrif's answer, which is to use:

var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url;

This will only work if you have the correct permissions, but will at least allow you to do what you want.

Just use the crossOrigin attribute and pass 'anonymous' as the second parameter

var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url;

This method will prevent you from getting an 'Access-Control-Allow-Origin' error from the server you are accessing to.

var img = new Image();
var timestamp = new Date().getTime();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url + '?' + timestamp;

Try the code below ...

<img crossOrigin="anonymous"
     id="imgpicture" 
     fall-back="images/penang realty,Apartment,house,condominium,terrace house,semi d,detached,
                bungalow,high end luxury properties,landed properties,gated guarded house.png"
