Add alt text to logo image

[hcann-edu]

Hi, How do I add alt text e.g. alt="Logo Image" to logo image for accessibility purposes? Wondering if it can be added in example 3 under:

//Page header
    public function Header() {
        // Logo
        $image_file = K_PATH_IMAGES.'logo_example.jpg';
        $this->Image($image_file, 10, 10, 15, '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false, false);
        // Set font
        $this->setFont('helvetica', 'B', 20);
        // Title
        $this->Cell(0, 15, '<< TCPDF Example 003 >>', 0, false, 'C', 0, '', 0, false, 'M', 'M');
    }

Thanks
