I'm trying to get a feel for some image manipulation in HTML5. I am finding that when I try and use the getImageData method I get this JS exception thrown. I am using Chrome and running on localhost.

It could be an issue with editing files on your local system using Chrome. You can close Chrome and reopen it using flags --allow-file-access-from-files to allow local file editing.
Came across this post when I ran into a similar issue and it helped.
