Unicalization images in the page with number

Can you implement unicalization for images with same post name in alt text? For example by adding image number to text end: if page content 3 images and post name is “My post name”, alt text for first image will be My post name – 1, for second My post name – 2, for third My post name – 3… I implement it in DomHelper trait setEmpty()/setNotEmpty() static function as third variable with default null value, but after updating it will be lost.

// DomHelper
public function setEmpty($option, $node, $img_url, $num = null)
{
    if ( Option::check($option) ) {
        $numText = $num ? ' - ' . $num : '';

        switch ( Option::get($option) ) {
            case Option::get($option) == 'alt_empty_fkw':
                $node->setAttribute("alt", $this->focus_keyword() . $this->site_title() . $numText);
                    break;
...

// DomController
$imagesNodes = $html->query( "https://img" );

for ($i = 0; $i < count($imagesNodes); $i++ ) {
    $node = $imagesNodes[$i];
    // Return image URL
    $img_url = $node->getAttribute( "src" );
    // Set alt for Post & Pages
            
    if ( is_singular( array( 'post', 'page' ) ) ) {
        $index = $i + 1;
