First we want to decode the URL and get the url parameter. We can do that using BalusC's great code for parsing query Strings. Then we just have to split that URL by / and take the last part. 

String url ="http://m.people.com/img/ic?width=474&height=269&fsize=999000&format=jpg&url=http%3A%2F%2Fimg2.timeinc.net%2Fpeople%2Fi%2F2011%2Fnews%2F110425%2Fgwyneth-paltrow-300.jpg";
Map<String, List<String>> params = new HashMap<String, List<String>>();
String[] urlParts = url.split("\\?");
if (urlParts.length > 1) {
    String query = urlParts[1];
    for (String param : query.split("&")) {
        String[] pair = param.split("=");
        String key;
        try
        {
          key = URLDecoder.decode(pair[0], "UTF-8");
        } catch (UnsupportedEncodingException e)
        {
          key = URLDecoder.decode(pair[0]);
        }
        String value;
        try
        {
          value = URLDecoder.decode(pair[1], "UTF-8");
        } catch (UnsupportedEncodingException e)
        {
          value = URLDecoder.decode(pair[1]);
        }
        List<String> values = params.get(key);
        if (values == null) {
            values = new ArrayList<String>();
            params.put(key, values);
        }
        values.add(value);
    }
}
String img = params.get("url").get(0);
String[] parts = img.split("/");
String imgName = parts[parts.length - 1];
System.out.println(imgName);
