android listview imageview,Android ImageView from ListView

I'm trying to pass KEY_THUMB_URL to SingleMenuItemActivity.class to show Image onclick listview. I have marked those area //Not Working . Please correct my codings, I'm pretty new to android.

CustomizedListView.class

public class CustomizedListView extends Activity {

// All static variables

static final String URL = "http://api.androidhive.info/music/music.xml";

// XML node keys

static final String KEY_SONG = "song"; // parent node

static final String KEY_ID = "id";

static final String KEY_TITLE = "title";

static final String KEY_ARTIST = "artist";

static final String KEY_DURATION = "duration";

static final String KEY_THUMB_URL = "thumb_url";

ListView list;

LazyAdapter adapter;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

ArrayList> songsList = new ArrayList>();

XMLParser parser = new XMLParser();

String xml = parser.getXmlFromUrl(URL); // getting XML from URL

Document doc = parser.getDomElement(xml); // getting DOM element

NodeList nl = doc.getElementsByTagName(KEY_SONG);

// looping through all song nodes

for (int i = 0; i < nl.getLength(); i++) {

// creating new HashMap

HashMap map = new HashMap();

Element e = (Element) nl.item(i);

// adding each child node to HashMap key => value

map.put(KEY_ID, parser.getValue(e, KEY_ID));

map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));

map.put(KEY_ARTIST, parser.getValue(e, KEY_ARTIST));

map.put(KEY_DURATION, parser.getValue(e, KEY_DURATION));

map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL));

// adding HashList to ArrayList

songsList.add(map);

}

list=(ListView)findViewById(R.id.list);

// Getting adapter by passing xml data ArrayList

adapter=new LazyAdapter(this, songsList);

list.setAdapter(adapter);

// Click event for single list row

list.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView> parent, View view,

int position, long id) {

String title = ((TextView) view.findViewById(R.id.title)).getText().toString();

String description = ((TextView) view.findViewById(R.id.artist)).getText().toString();

// Starting new intent

Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);

in.putExtra(KEY_TITLE, title);

in.putExtra(KEY_THUMB_URL, R.id.list_image); //Modified as told by Nandeesh

in.putExtra(KEY_ARTIST, description);

// int thumb_image = in.getIntExtra(KEY_THUMB_URL); // ERROR : The method getIntExtra(String, int) in the type Intent is not applicable for the arguments (String)
