Wordpress & picturefill implementation -


i'm trying implement responsive image in wordpress theme. there few plug-ins available ones tried messed layout.

what replace existing images (not featured images or thumbnails) responsive images, either srcset or

my wordpress theme creates following image sizes:

add_image_size( "maximal", "1900" ); add_image_size( "desktop", "1405" ); add_image_size( "tablet", "981" ); add_image_size( "smalltablet", "768" ); add_image_size( "mobile", "479" );

i have tried replace img tags preg_replace function have never managed capture images , i'm not sure if it's best way it. of images have classes, don't.

in end, replace simple image this:

<img src="<destination"> id="<id>" class="<class">

by this:

<picture> <source srcset="<img src mobile" media="(max-width: 500px)"> <source srcset="<img src small tablets" media="(min-width: 700px)"> <source srcset="<img src tablets" media="(min-width: 950px)"> <source srcset="<img src desktop" media="(min-width: 1200px)"> <source srcset="<img src big screens" media="(min-width: 1600px)"> </picture>

the srcset equivalent ok.

thanks! laurent

i think filter post_thumbnail_html trick,, code should this..

add_filter('post_thumbnail_html', 'picturefill_html', 99, 5); function picturefill_html(){     $id = get_post_thumbnail_id(); // attachment id     $src_small = wp_get_attachment_image_src($id, 'smalltablet'); // new image size url     $src_large = wp_get_attachment_image_src($id, 'maximal'); // new image size url     $class = $attr['class'];      $html = '     <picture>         <source srcset="'.$src_small[0].'" media="(max-width: 500px)">         <source srcset="'.$src_large[0].'" media="(min-width: 1200px)">     </picture>     ';      return $html; }
