作为一个JS新手 看得有点纠结 在图片上加超链接添<A>标签就可以了
具体代码

a=str[parseInt(Math.random()*(str.length))]
document.write("<a href='此处即为链接代码'><img src="+a+"></a>")

首先
if (oImg.src="img/1.png")
是赋值而不是判断相等, 判断相等请用==或者===
其次, 你的切换不应当依赖於从元素上读到的src, 而应当用变量维护当前的状态
示例
window.onload = function(){
var
oImg = document.getElementById('img1'),
Picture = ['img/1.png','img/2.png'],
Index = 0
oImg.onclick = function()
{
++Index
Index < Picture.length || (Index = 0)
oImg.src = Picture[Index]
}
}
