推荐答案
假设它是顶部的两个图像，您可以执行以下操作:
Guessing it is the two images in the top, you could do this:
<div>
<a class="expand_all" style="display: none;" onclick="$('.expand_all').hide();$('.collapse_all').show()">
<img class="img-swap" src="images/toggle-buttons_01.png">
</a>
<a class="collapse_all" onclick="$('.expand_all').show();$('.collapse_all').hide()" style="display: inline;">
<img alt="" src="images/toggle-buttons_02.png">
</a>
</div>
简单地隐藏不相关的图片....虽然不是真正交换图片.
Simply hiding the irrelevant one....not really swapping images though.
