# Featured Image srcset

 * Using TwentyFifteen theme, brand new post, with a new image.
 * When setting the Featured image, there is no srcset, various image sizes, set
   by this plugin. There is just a single image size.
 * However, embedding the same image in the same post does set a srcset with various
   sizes dictated by this plugin.
 * So, how do I get the Featured image to behave the same way? I thought this plugin
   handles it automatically.
 * > Whenever WordPress outputs the image through the media uploader, or whenever
   > a featured image is generated, those sizes will be included in the image tag
   > via the srcset attribute.

 * Hi Polyfade,
 * TwentyFifteen uses a specific custom crop for header images, which are exactly
   825×510 pixels. In order for our plugin to add a srcset attribute, you would 
   need to have other image sizes available at the exact same aspect ratio.
 * For example, if you added another image size that was 440×272, through a functions.
   php file in a child theme, you would see srcset attributes containing both image
   sizes.

 * [@joe](https://wordpress.org/support/users/joe/) McGill, thanks. I’m realizing
   that now looking at the way thumbnail is being declared as `twentyfifteen_post_thumbnail()`
   instead of the common `the_post_thumbnail()`. As you mentioned the thumbnail 
   options are set to crop `set_post_thumbnail_size( 825, 510, true )`.
