Можно ли загрузить base64 или blob в wordpress галерею?

function blobToFile(theBlob, fileName){
    theBlob.lastModifiedDate = new Date();
    theBlob.name = fileName;
    return theBlob;
  }

  function ajaxUploadFiles(e) {
    $(e.target).parent().hide();
    $overlay.hide();

    var loader = $('.loader-wrapper');
    loader.css('display', 'flex');

    var opts = {
      width: 900,
      heght: 300
    };

    imageCropper.getCroppedCanvas(opts).toBlob(function (blob) {
      var fd = new FormData();

      var filename = 'slider-img_' + new Date().getTime() + '.jpg';
      var file = blobToFile(blob, filename);

      console.log(file);
      fd.append('photo', file, filename);
      fd.append('action', 'wis_load_image');
      $.ajax({
        type: 'POST',
        url: ajaxurl,
        data: fd,
        processData: false,
        contentType: false,

        success: function (response) {
          var $html = $(response.html);
          $html.appendTo($('.wis_slider_list ul'));

          loader.fadeOut();
        },
        error: function (e) {
          alert(e.responseJSON.data.error);
          loader.fadeOut();
        }
      });
    }, 'image/jpeg');
    imageCropper.destroy();
  }
