I have a multilingual WordPress site using WPML plugin which allows to have separate domains that point to the same WordPress install.

I’m implementing this script to make grayscale images on the fly

I previously tried pure CSS methods with the filter property but it slows down the site, plus it doesn’t work in IE10

I am serving images and script from the respective domain in each case (.nl and .com), so I don’t understand why there’s a security error.

Error messages in IE10

the error seems to happen here:

SCRIPT5022: SecurityError 
homepage.js, line 37 character 2

var imgPixels = ctx.getImageData(0, 0, canvas.width, canvas.height);

In Firefox

SecurityError: The operation is insecure.
[Break On This Error]   

var imgPixels = ctx.getImageData(0, 0, canvas.width, canvas.height);

any help appreciated

thanks
