Answer 1

您可以尝试使用javascript

<button id="mybutton" onclick="showButton()">Show Image </button>

function showButton(){
  image = document.getElementById('nameOfImageHere');
  image.style.display = "block";
}

Answer 2

我们走了：

1方法：您可以使用jQuery Hide（），Show（）函数：

          <script>
            $(document).ready(function(){
                $("#buttonIdShow").click(function(){
                    $("#Image").hide();
                });
                $("#buttonIdHide").click(function(){
                    $("#Image").show();
                });
            });
            </script>



        <img id="Image"/>               <!-Here is your image-->
    <button type="button" id="buttonIdShow">Show</button>  <!--Show button-->

    <button type="button" id="buttonIdHide">Hide</button> <!--Hide button-->

2方法：jQuery Animate CSS显示：

<script>
$("#yourButton1Id").click(function(){
  $("#ImageId").css("display","block");
});

$("#yourButton2Id").click(function(){
  $("#ImageId").css("display","none");
});
</script>

希望它有所帮助;）
