Refactor your method to be check weather the check box is checked instead of checking the image equity:

private void pictureBox94_Click(object sender, EventArgs e)
{
    if (!checkBox3.Checked)
    {
        pictureBox94.Image = Properties.Resources.select;
    }
    else
    {
        pictureBox94.Image = Properties.Resources.vuoto;
    }

    checkBox3.Checked = !checkBox3.Checked;
}
