1. No matter how I write it, I can"t get the picture object
2. It"s going crazy!

<input type="file" onchange="upimgfun">

function upimgfun(e){
     alert(e)
     e.target.files[0]
}

<input type="file" class="upimg">

$(".upimg").change(function(e){
 alert($(this))
})

this is the code. No matter how you write it, you don"t even play it.
