Fragment mit Image aktualisieren

Hallo, habe folgendes Problem.
Habe nen viewpager mit Fragmenten(je mit einem bild)...beim starten der activity werden die URLs der einzelnen, auf einem webserver gespeicherten bilder, geholt und je ein Default Fragment erzeugt..anschließend werden die einzelnen bilder geladen und sollen angezeigt werden bzw dynamisch nachgeladen werden..soweit so gut
momentan funktioniert es zwar, aber noch nicht so ganz...wenn man auf einem Default Fragment ist, wird das bild leider nicht automatisch geladen...sondern erst bei recreate des fragments..hatte gehofft das sollte per Pager.notifyDataSetChanged funktionieren...irgendwelche Ideen?

[code]
public class UserProfilePub_viewpager extends FragmentActivity {
UserProfilePub_viewpager actRef = this;
Bitmap profilePic;
int pos;
static String picturePath=null;
int index;
final static int RESULT_LOAD_IMAGE = 2;
//private static int NUM_PAGES = 3;
private ViewPager mPager;
private PagerAdapter mPagerAdapter;

ImageView imgView;

ArrayList<Fragment> fragments = new ArrayList<Fragment>();
ArrayList<Bitmap> pics = new ArrayList<Bitmap>();

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.viewpager_layout_activity);

Intent intent = getIntent();
String USID = intent.getExtras().getString("USID");
profilePic = intent.getExtras().getParcelable("profilePic");
List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
nameValuePair.add(new BasicNameValuePair("USID", USID));

UserProfilePub_getImageUrl upp_getImageUrls = new UserProfilePub_getImageUrl(nameValuePair, url, null, this);
upp_getImageUrls.execute();
Button button1 = (Button) findViewById(R.id.btn_viewpager_newPic);
button1.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, RESULT_LOAD_IMAGE);
}

});

fragments.add(new ScreenSlidePageFragment().newInstance(profilePic, true, pics, 0)); mPager = (ViewPager) findViewById(R.id.pager);
mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager(), fragments);
mPager.setAdapter(mPagerAdapter);

}

// UserProfilePub_getImageUrl - Asynctask ruft folgende Methode auf:

public void savePicUrls(String result){
String[] urls = result.toString().split(",");

for(int i=0; i<urls.length; i++){
