    <i>In the "Varied image responses" mode, WebP Express creates redirection rules for images, such that a request for a jpeg will
        result in a webp &ndash; but only if the request comes from a webp-enabled browser. Note that not all CDN's handles varied responses well (see FAQ).

            Benefits of not varying image responses:
            <ol>
                <li>CDN's will not have to be set up to forward the Accept header</li>
                <li>Better HIT ratio on CDNs, if the CDN had to be configured to vary on the whole Accept header.</li>
                <li>If a user downloads an image, it will not have wrong file extension</li>
            </ol>
            PS: This mode also works great with <a target="_blank" href="https://da.wordpress.org/plugins/cache-enabler/">Cache Enabler</a>. Instructions are found in the FAQ.
        </p>
        <p>
            PPS: Images refererenced from external CSS or added dynamically with javascript will not be served as webp in this mode.

        <i>The "No conversion" mode is for scenarios where you are using another plugin for converting images.
        Perhaps the other plugin doesn't have the redirection or alter HTML feature, or perhaps it doesn't do it as well
        as WebP Express does. PS: The two methods below works great in tandem.</i>
