 * Hi there,
 * I’m playing around with the idea to switching to blocksy, but I have a question
   about responsivness.
 * I let WordPress create a thumbnail image with 200 pixel, a medium size image 
   with 400 pixel big size is zero, because I load up an optimized webp image with
   800 pixel.
 * 800 pixel is the size for my featured image on my blogposts on desktop, but it
   loads on mobile too with 800 pixel altough I have a medium size image with 400
   pixels.
 * Can Blocksy load the featured image in different sizes for different viewports
   like desktop / tablet and mobile and uses it the created alternative images for
   that or I have to install an extra plugin like shortpixel adaptive images?
 * Thank you in advance for your answer and best regards
 * Marc

 * Hello [@jackmac71](https://wordpress.org/support/users/jackmac71/)
 * WordPress already loads the appropriate image for each device. But, as with today’s
   technology, screen densities are very high, which means that the full resolution
   image must be loaded as otherwise it would look pixelated. If you look very closely
   at the source code of the featured image (or pretty much any other image), you
   will see that it has a `srcset` parameter – this is the one that controls which
   image is loaded for each device. You can read up more on this here – [https://docs.imgix.com/getting-started/tutorials/responsive-design/responsive-images-with-srcset](https://docs.imgix.com/getting-started/tutorials/responsive-design/responsive-images-with-srcset).
 * I wouldn’t advise you to modify this system, as it can break some scenarios. 
   But if you need to modify it, it would be advisable to implement a specialised
   plugin or additional code.
 * Hope this clears things up!
 * Thanks.
