Why might there be such an error?

вот так на картинку вписывается текст.

public static void Pechat()
{
string FirstText = "привет Лолзтим, ты крут";
string[] array = FirstText.Split(' ');
int counterOfWords = 0;
float horizontal = 250;
float verticalForChertej = 150;

float horizontal1 = 260;
float vertica1l = 135;

float horizontal2 = 120;
float vertical2 = 150;

int x = 20;

for (int i = 0; i < array.Length; i++)
{
counterOfWords++;
}
if (counterOfWords > 2)
{
int counter = 0;

Image img = Bitmap.FromFile(@"D:\scriptscheats\sert.jpg");
for (int i = 0; i < counterOfWords; i++)
{

if (counter < 7)
{
++counter;
Graphics graph = Graphics.FromImage(img);
graph.DrawString(array[i], new Font("MS Reference Sans Serif", (float)6.5), new SolidBrush(Color.Gray), horizontal1, vertica1l);
horizontal1 += 35;
graph = null;
//img = null;
}
else
{
Graphics graph = Graphics.FromImage(img);
graph.DrawString(array[i], new Font("MS Reference Sans Serif", (float)6.5), new SolidBrush(Color.Gray), horizontal2, vertical2);
horizontal2 += 25;
graph = null;

}

}
img.Save(@"D:\scriptscheats\sert" + "1" + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
MessageBox.Show("Выполнено");
}
else if (counterOfWords <= 2)
{
