Why does canvas.toDataURL() throw a security exception?

Question

Did I not get enough sleep or what? This following code

var frame=document.getElementById(\"viewer\");
frame.width=100;
frame.height=100;

var ctx=frame.getC         


        

Answer 1

If you are simply drawing some images on a canvas, make sure you are loading the images from the same domain.

www.example.com is different to example.com

So make sure your images and the url you have in your address bar are the same, www or not.
