• (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info
  {
  [self dismissViewControllerAnimated:YES completion:nil];

  for (UIView *v in [_scrollView subviews]) {
  [v removeFromSuperview];
  }

  CGRect workingFrame = _scrollView.frame;
  workingFrame.origin.x = 0;

  NSMutableArray *images = [NSMutableArray arrayWithCapacity:[info count]];
  for (NSDictionary dict in info) {
  if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypePhoto){
  if ([dict objectForKey:UIImagePickerControllerOriginalImage]){
  UIImage image=[dict objectForKey:UIImagePickerControllerOriginalImage];
  [images addObject:image];

            UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
            [imageview setContentMode:UIViewContentModeScaleAspectFit];
            imageview.frame = workingFrame;
