Fails WCAG 2.0 A Validation by Total Validator

There is exactly one error that prevents this theme from passing WCAG 2.0 A, AA, or AAA. The error is as follows:

198 E650 The default style sheet language must be specified when style attributes are used:

The E650 error summary is as follows:

E650 - 1 instance(s): When style attributes are used the default style sheet language should be specified using a Content-Style-Type HTTP header or tag. See http://www.w3.org/TR/html401/present/styles.html#h-14.2.1.

There are two solutions:

1. Generate a Content-Type-Style meta tag
2. Use the attributes of the img tag and not the style tag to specify border, height, and width.

In my opinion the second option is easier.
