首先使用jquery选择器获取到想要绑定click事件的img元素，然后可以直接绑定click方法，也可以通过bind方法绑定。这里详细介绍一下bind方法。
jQuery 事件 - bind() 方法 —— 定义和用法
bind() 方法为被选元素添加一个或多个事件处理程序，并规定事件发生时运行的函数。
jQuery 事件 - bind() 方法 ——将事件和函数绑定到元素
规定向被选元素添加的一个或多个事件处理程序，以及当事件发生时运行的函数。

jQuery 事件 - bind() 方法——语法
$(selector).bind(event,data,function)
jQuery 事件 - bind() 方法——参数描述
event 必需。规定添加到元素的一个或多个事件。由空格分隔多个事件。必须是有效的事件。
data 可选。规定传递到函数的额外数据。
function 必需。规定当事件发生时运行的函数。
实例：
//直接给所有img标签绑定click事件
$("img").click(function(){
alert('你点击了图片');
})
//使用bind方法绑定click事件
$("img").bind("click",function(){
alert('你点击了图片');
})Html 的img标签添加点击事件
