hello i am searching for a way to make images responsive in my theme.
I would like to know if it's possible to dynamicly change the images source by screen size, to be able to display a smaller image when a user visits my website using a mobile phone or tablet.
desktop url: image-1024.jpg
tablet url: image-720.jpg
mobile url image-320.jpg
like the above example, is there a possibility to change these while resizing the browser?
how does it work with caching? will it be posible for my visitors on desktop to get a cached page with mobile images?
I would like to hear what is possible.
