두 이미지를 나란히 가운데에 배치하는 방법은 무엇입니까?

<code class="css">#fblogo {
    display: block;
    margin-left: auto;
    margin-right: auto;
    height: 30px; 
}</code>

<code class="css">.fblogo {
    display: inline-block;
    margin-left: auto;
    margin-right: auto;
    height: 30px; 
}

#images{
    text-align:center;
}</code>

<code class="html"><div id="images">
    <a href="mailto:[email&#160;protected]">
    <img class="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp-content/uploads/2012/07/email-icon-e1343123697991.jpg"/> </a>
