    CGSize itemSize = CGSizeMake(img.size.width *2/3, img.size.height *2/3);
    UIGraphicsBeginImageContext(itemSize);
    CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height);
    [cell.imageView.image drawInRect:imageRect];
    cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
