I want to show images in my community topics/posts.

i do this with this code.

add_filter('wpforo_content_after', function( $content ){
	return preg_replace_callback(
        '#<a[^><]*\sclass=[\'\"](?:[^\'\"]*\s)?wpforo-default-attachment(?:\s[^\'\"]*)?[\'\"][^><]*\shref=[\'\"]([^\"\']+)[\'\"][^><]*>.*?</a>#isu',
        function( $match ){
                $html     = $match[0];
	        $file     = $match[1];
	        $pathinfo = pathinfo( $file );
	        if( wpforo_is_image($pathinfo['extension']) ) {
                $html = sprintf(
                    '<a href="%1$s" target="_blank"><img class="wpforo-default-image-attachment" src="%1$s" alt="%2$s" title="%2$s"></a>',
	                esc_url($file),
	                esc_attr($pathinfo['basename'])
                );
	        }
            return $html;
        },
        $content
    );
}, 11);

But i have to add this code after every update. Is there any other way to fix this issue.
