Ajax图像上传 - 获取完整图像（wordpress）

Question

I'm trying to access the full image when I upload to a form. I know how to access the thumbnail image of course but have no clue how to access the original unmodified one. console.log(data) only shows two parameters Thumbnail and ID.

Please let me know if you need additional file information, thank you.

javascript file:

//add pin from computer
    $('#pin_upload_file').change(function() {
        $('.error-msg').hide();
        $('#pin_upload_form').submit();
    });

    if ($('#pin_upload_form').length) {
        var options = {
            beforeSubmit: showRequest,
            uploadProgress: function(event, position, total, percentComplete) {
                if (window.FormData !== undefined) {
                    $('#pin-upload-progress').show();
                    $('#pin-upload-progress .progress-bar-text').text(percentComplete + '%');
                    $('#pin-upload-progress .progress-bar').css('width', percentComplete + '%');
                }
            },
            success: showResponse,
            url: obj_ipin.ajaxurl
        };
        $('#pin_upload_form').ajaxForm(options);
    }

    function showRequest(formData, jqForm, options) {
        $('#pin-upload-from-web-wrapper, #browser-addon, #bookmarklet, #pinitbutton').slideUp();
        if (window.FormData === undefined) {
            $('#pin-upload-from-computer-wrapper .ajax-loader-add-pin').show();
        }

        var ext = $('#pin_upload_file').val().split('.').pop().toLowerCase();
        if ($.inArray(ext, ['gif', 'png', 'jpg', 'jpeg']) == -1) {
            $('#pin-upload-from-computer-wrapper .ajax-loader-add-pin, #pin-upload-progress').hide();
            $('.error-msg').html('<div class="alert alert-warning"><strong>' + obj_ipin.__invalidimagefile + '</strong></div>').fadeIn();
            return false;
        }
    }

    function showResponse(responseText, statusText, xhr, $form) {
        if (responseText == 'error') {
            $('.ajax-loader-add-pin, #pin-upload-progress').hide();
            $('.error-msg').html('<div class="alert alert-warning"><strong>' + obj_ipin.__invalidimagefile + '</strong></div>').fadeIn();
        } else if (responseText == 'errorsize') {
            $('.ajax-loader-add-pin, #pin-upload-progress').hide();
            $('.error-msg').html('<div class="alert alert-warning"><strong>' + obj_ipin.__imagetoosmall + '</strong></div>').fadeIn();
        } else {
            var data = $.parseJSON(responseText);
            $('#thumbnail').attr('src', data.thumbnail);
            $('#attachment-id').val(data.id);
            $('.ajax-loader-add-pin, .error-msg, #pin-upload-progress').hide();
            $('#pin-upload-from-computer-wrapper').slideUp(function() {
                $('#pin-upload-postdata-wrapper').slideDown();
                $('#pin-postdata-form #pin-title').focus();
            });
        }
    }
