A bit confused as to how to get responsive images working?

[AdamDSherman]

Describe your problem/question
I've linked up lazysizes to my site no issues. Adding the lazyload class seems to work. However, I cannot figure out how to swap out images at different break points.

Make it reproduce-able
I have the line:

<img data-srcset="medium.jpg 768w, small.jpg 634w" data-src="small.jpg 634w" data-size="auto" class="lazyload">

But no matter what screen size I have it will always display the medium image.

How do I get it to display the smaller image?

Many thanks!

Hi Adam,

Here is an example of a normal image with webp and jpg fallback.

the class img-responsive:

width: 100%; height:auto;

Image ratio = in this case 3:2 but can be any ratio!

Here a header with art direction for mobile phones
phone = ratio 4:3
wide = ratio 4:1
But you can make it the way you want!
