Hello

My apologies if this is the wrong format. First post.

Images are responsive in Gmail android app, but images in android mail show at their natural size - blowing out the width of the newsletter. I'm using this method: http://webdesign.tutsplus.com/articles/build-an-html-email-template-from-scratch--webdesign-12770

Code below. Any advice would be highyl appreciated. Thank you

    <center class="wrapper" style="width: 100%;table-layout: fixed;-webkit-text-size-adjust: 100%;-ms-text-size-adjust: 100%;">
        <div class="webkit" style="max-width: 600px;">
            <tr>
            <td>
            <table class="outer" align="center" style="border-spacing: 0;font-family: sans-serif;color: #333333;margin: 0 auto;width: 100%;max-width: 600px;">
                <tr>
                    <td class="full-width-image" style="padding: 10px 20px 0 20px;">
                        <img alt="Hero" src="http://www.vision6.com.au/download/files/45236/1742688/updatedetails_hero.jpg" style="display: block;text-align: center;width: 100%;height: auto;border: 0 none;max-width: 600px;" />
                    </td>
                </tr>
            </table>
            </td>
            </tr>
        </div>
    </center>
