the problem should be on the parameter processData , please add the parameter processData: false, to your ajax request and try to get your image on the php.

            $.ajax({
                url: formURL,
                type: form.attr('method'),
                dataType: 'json',
                data: formData,//form.serialize(),
                processData: false,  // tell jQuery not to process the data
                contentType: false,   // tell jQuery not to set contentType
                beforeSend: function(){},
                success: function(data, textStatus, jqXHR) {},
                error: function(jqXHR, textStatus, errorThrown) 
               {
                  alert(jqXHR+ textStatus+ errorThrown);
                },
              complete: function(){}
                });

Place your inputs properly in one form and use FormData() to send the form as a whole. I would suggest something like this :

<form method="post" enctype="multipart/formdata" id="myForm">
   <input type="text" name="title" />
   <input type="file" name="thumbnail" />
</form>

Build and send the data with js :

var form = document.getElementById('myForm');
var formData = new FormData(form);

alert (formdata);

$.ajax({
    url: "php/post-check.php",
    type: "POST",
    data: formData,
    success: function (data) {
        $("div#postresult").removeClass("alert alert-danger");
        $("div#postresult").html(data);
    }
});

Now you can get the data in php like this way :

$title = $_POST['title'];
$thumb = $_FILES['thumbnail'];
$tmp_file_path = $thumb['tmp_name'];

You could just post the entire form in async using ajaxForm() like this:

$("#newpost").ajaxForm({
    success: function(data) {
        $("div#postresult").removeClass("alert alert-danger");
        $("div#postresult").html(data);
    },
    error: function(a, textStatus, exception) {

    }
});

AjaxForm is not part of core JQuery but you can find the source here and the documentation here
