    self.commentLabelHeightConstraint.constant = commentLabelSize.height + 20;
    self.imageHeightConstraint.constant = self.mediaItem.image.size.height / self.mediaItem.image.size.width * CGRectGetWidth(self.contentView.bounds);

    // Hide the line between cells
    self.separatorInset = UIEdgeInsetsMake(0, 0, 0, CGRectGetWidth(self.bounds));
}
