Menu
We have to display image after selecting file in input(type='file') using JavaScript. We can preview input file(image) with following 'readURL' user defined JavaScript function. The Preview action executed when input 'onchange' event trigged.
First, open the html file you are editing from the File : Open dialog, or from the Open File icon on the toolbar. Click on the toggle Browser Preview on the toolbar or from the View menu. This will give you a quick browser preview. Click on the button again and it will return to the code view.

reader.readAsDataURL(input.files[0]);
}
}
Live Demo
You can achieve this with the following code:
$("input").change(function(e) {
for (var i = 0; i < e.originalEvent.srcElement.files.length; i++) {
var file = e.originalEvent.srcElement.files[i];
var img = document.createElement("img");
var reader = new FileReader();
reader.onloadend = function() {
img.src = reader.result;
}
reader.readAsDataURL(file);
$("input").after(img);
}
});

This can be done using HTML5, but will only work in browsers that support it. Here's an example.
Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.
