Here is a screenshot of what I have:

Here is a screenshot of what I would like:

The current HTML is:

    <div id="footer">
        <div class="lower"><img src="images/one.jpg" alt="Ring being put on finger"/></div>
        <div class="lower"><img src="images/two.jpg" alt="The mens trousers"/></div>
        <div class="lower"><img src="images/three.jpg" alt="Flowers"/></div>
        <div class="lower"><img src="images/four.jpg" alt="The rings"/></div>
    </div>

and the CSS is

#footer {
  display: table;
  width: 100%;
  max-width: 1024px;
  margin-top: 1%;
}

.lower {
  display: table-cell;
}

#footer img {
  width: 100%;
  height: auto;
  max-width: 256px;
}

Please bear in mind that this is a responsive webpage so I would like the space to always remain however I would like the space to change according to device size, so using %.
