NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

  NSString *documentsDirectory = [paths objectAtIndex:0];
  NSArray *filePathsArray = [[NSFileManager defaultManager]                                                       
  subpathsOfDirectoryAtPath:documentsDirectory  error:nil];






for (int i=3; i<[filePathsArray count]; i++)
{    
    NSString *strFilePath = [filePathsArray objectAtIndex:i];

    NSString *fullpath = [NSString stringWithFormat:@"%@/%@",documentsDirectory,strFilePath];

    NSLog(@"array with paths of image files in the Document Directory %@", fullpath);


    UIImage *myImage = [UIImage imageWithContentsOfFile:fullpath];

    NSLog(@"array with paths of image files in the Document Directory %@", myImage);

    UIImageView *img = [[UIImageView alloc] init];
    img.image = myImage;


    CGFloat xOrigin = (i - 3) * 320.0f;

    img.frame = CGRectMake(xOrigin,-64,320,117);
    [_scrollViewProperty  addSubview:img];

}
