Just put the image link on the dropdown button. See below code
只需将图像链接放在下拉按钮上。看下面的代码
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

<div class="container">
<h2>Dropdowns</h2>
<p>The .dropdown with image link.</p>
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="menu1" data-toggle="dropdown">
<img src="http://placehold.it/350x150">
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="menu1">
<li role="presentation"><a role="menuitem" tabindex="-1" href="#">Menu item 1</a></li>
<li role="presentation"><a role="menuitem" tabindex="-1" href="#">Menu item 2</a></li>
<li role="presentation"><a role="menuitem" tabindex="-1" href="#">Menu item 3</a></li>
<li role="presentation" class="divider"></li>
<li role="presentation"><a role="menuitem" tabindex="-1" href="#">Menu item 4</a></li>
</ul>
</div>

If you want a pure image as the dropdown toggle, you can use an anchor (a) instead of a buttonto have only the image displayed.
如果您想要一个纯图像作为下拉切换开关，您可以使用锚点 ( a) 而不是 abutton来仅显示图像。
