 * thanks for this plugin and great to see people thinking about speed….
 * 1. Can you explain to me how WP is generating the featured image? I thought it
   was just using the thumbnail setting in WP to generate that featured image. From
   your description, WP is using a image srcset to deliver the thumbnail size according
   to the screen size, which is not useful on smaller screen (screen size vs net
   speed)
 * 2. is there a way to auto generate this mobile thumbnail, automatically?
 * thanks

 * Hey [@expat](https://wordpress.org/support/users/expat/)!
 * Let me see if I can clarify how WordPress handles the image tag and how this 
   plugin modifies that code.
 * 1. WordPress creates an image tag that looks something like my sample below. 
   There’s the standard `src` attribute that defines the basic image path. WordPress
   also adds the `srcset` attribute that contains a number of different sizes for
   your featured image. Smaller devices will load a smaller image (since they don’t
   need the large version needed for a big monitor). The number after an image name
   determines what size screen will load that image. `959w` will load on any screen
   that is 959 pixels wide or less.
 *     ```
       <img 
           src="my-featured-image.jpg" 
           srcset="my-featured-image.jpg 4288w, 
                   my-featured-image-1024x373.jpg 1024w, 
                   my-featured-image-959x349.jpg 959w" 
           sizes="100vw" >
       ```
   
 * 2. In terms of auto generating the mobile thumbnail, WordPress already does that
   for you! When you upload an image WP will make several different versions of 
   it at different image sizes. And the `srcset` attribute will automatically apply
   the mobile thumbnail to mobile devices. One small thing to note – your theme 
   defines what image sizes get created, and each theme creates different image 
   sizes.
 * I hope that answers your questions. If not, let me know.
