Error reading image file in IE11

Hi there,

When I try to read an image file in IE11, it fails with this error:
Object doesn't support property or method 'readAsBinaryString'.

Thanks,

Update: looks like reader.readAsBinaryString(file) is not supported by IE.

The upload works after changing to reader.readAsDataURL(file);
