Lazy Loader

Yes. See the following example that would generate lazy-load-ready output for the result of the not-supported wp_get_attachment_image() function: global $lazy_loader; if ( isset( $lazy_loader ) && $lazy_loader instanceof FlorianBrinkmann\LazyLoadResponsiveImages\Plugin ) { echo $lazy_loader->filter_markup( wp_get_attachment_image( 1261 ) ); } To make it happen, you need to pass the markup that contains the image (or images) to $lazy_loader->filter_markup(). The if statement ensures that the Lazy Loader object is there and that it is an object of the correct class.

Important: If you modify or remove the inline styles, also the style that shows the loading spinner is affected. So if you remove the styles or modify them without adding back the spinner styles, the spinner option will not work. I created a Gist with the spinner styles – just add them to your modification to make it work. To disable or modify the plugin’s inline styles (except the style that hides the img.lazyload elements when JS is disabled, so only the noscript version is displayed) you can use the lazy_load_responsive_images_inline_styles filter. For example, to remove the inline styles, use the following code: add_filter( 'lazy_load_responsive_images_inline_styles', function () { return ''; } ); If you want to modify it, you can do that like in the following code block (remember to include the opening and closing style tags for additions/replacements). The code modifies the duration of the fade-in-effect: ` add_filter( 'lazy_load_responsive_images_inline_styles', function ( $default_styles ) { $default_styles = sprintf( '%s :root { --lazy-loader-animation-duration: 600ms; }', $default_styles ); return $default_styles; } ); The CSS from the example are the default styles that are used by the plugin (without the loading spinner styles). Thedisplay: blockfor.lazyload` is important for the aspectratio plugin option.

There is a textarea in the plugin settings where you can insert custom settings for the lazysizes config.
