Are images cached?

Question

JavaScript

There is markup

<div id="slider">
      <div data-img="img/1.jpg"></div>
      <div data-img="img/2.jpg"></div>
      <div data-img="img/3.jpg"></div>
      <div data-img="img/4.jpg"></div>
</div>

Using js, I make the background of the block from the data-img attribute. Does the browser cache these images?

Answer 1

If the browser and server settings allow, then it caches. From the browser's point of view, a picture is a picture - no matter where exactly it was requested from.
