ドロップされた要素を保存する

こんにちは、度々すみません
今、monacaを使いドラッグアンドドロップでドロップされた画像をボタンクリックでローカルストレージに保存し、次のページで表示させようとしています。

そこで、ボタンをクリックすると画像（パス）をストレージに保存させようとしていますが
drop後のtrush内の値を保存させようと

$(function() {
  $("#next").click(onnext);
});

function onnext() {
    var gazo = $("#trash").html();
    var tes = {
        trash:gazo,  
    }
    console.log("#trush");

    localStorage.setItem("test", JSON.stringify(tes));
}

このようにしたのですが #trush をconsole.logで確認すると

#trush
{"trash":"\n    \n      Drop Items:1\n      \n    \n  \n      High Tatras\n      \n      \n    "}

このように表示され画像のパスが入っていません。
ドロップで #trush に画像が入っているから表示されていると思うのですが
#trush 内を取り出すと空に。。。
どうすればいいでしょうか、よろしくお願い致します。
