Question

Images

Answer 1

When using the image request functions, almost everyone has a $size parameter that you can pass in the size you want.

$img = wp_get_attachment_image( $attachment_id, $size, $icon, $attr );

Better yet, use the properties of the <img> srcset tag , where you can pass references to all available image sizes. Of these, the browser will be able to choose the most appropriate
