SARVAROV Lazy Load

常見問題集

Will that plugin work on any template?

I hope so, but might be not. I originally made this plugin for myself and I tested it only on latest WordPress release on the default Twenty Fifteen theme. If you have compatibility issues with my plugin and your theme – just write me and I will try to fix it on next update.

Why isn’t LQIP technologue working?

LQIP (Low Quality Image Placeholders) is working only on newly uploaded images (.jpg & .jpeg). If you want to make it work with existing images, you need to regenerate lqip image size using a third-party plugin like Regenerate Thumbnails.

How to make lazy custom images/iframes?

You can create a custom function like this:

function my_lazy_process( $content = '', $params = array() ) {

    if( class_exists( 'SARVAROV_Lazy_Load' ) ) {
        return apply_filters( 'lazy_process', $content, $params );
    }

    return $content;
}

Will this plugin affect SEO?

Definitely Yes, in a positive way. The pages of your site will load faster, which positively affects the indexing of your site by search engine robots. The plugin has no effect on image indexing: search engines see them, don’t worry!

How to add Schema.org vocabulary?

For example:

add_filter( 'sarvarov_lazy_load_image_container_atts', function( $atts ) {
    $new_atts = array(
        'itemprop' => array(
            'value' => 'image'
        ), 
        'itemscope' => array(
            'value' => 'itemscope'
        ), 
        'itemtype' => array(
            'value' => 'http://schema.org/ImageObject'
        )
    );

    $atts = array_merge(
        $atts,
        $new_atts
    );

    return $atts;
}, 10, 1 );

add_filter( 'sarvarov_lazy_load_image_container', function( $content = '', $img_width, $img_height, $atts ) {
    if( $img_width && $img_height ) {
        $content .= sprintf( '<meta itemprop="width" content="%1$d" /><meta itemprop="height" content="%2$d" />', $img_width, $img_height );
    }

    return $content;
}, 10, 4 );
