jQuery Code
jQuery(function($){

*/
$('body').on('click', '.misha_upload_image_button', function(e){
e.preventDefault();
var button = $(this),

library : {
// uncomment the next line if you want to attach image to the current post
// uploadedTo : wp.media.view.settings.post.id,
type : 'image'
},
button: {
text: 'Use this image' // button label text
},
multiple: false // for multiple image selection set to true
}).on('select', function() { // it also has "open" and "close" events
var attachment = custom_uploader.state().get('selection').first().toJSON();
$(button).removeClass('button').html('<img class="true_pre_image" src="' + attachment.url + '" style="max-width:95%;display:block;" />').next().val(attachment.id).next().show();
/* if you sen multiple to true, here is some code for getting the image IDs
var attachments = frame.state().get('selection'),
attachment_ids = new Array(),
i = 0;
attachments.each(function(attachment) {
attachment_ids[i] = attachment['id'];
console.log( attachment );
i++;
});
*/
})
.open();
});
/*
* Remove image event
*/
$('body').on('click', '.misha_remove_image_button', function(){
$(this).hide().prev().val('').prev().addClass('button').html('Upload image');
return false;
});
});
