Steps for choosing an image and embedding it within a div element

Upon loading the site, an image is displayed with the following code:

<img id="some_Image" src="some_source">

However, I am looking to avoid requesting this image again from "some_source". This is because calculating the image can be resource-intensive and I do not want to recalculate it. Instead, I plan to reuse the same image later on in a JQuery dialog. While I am aware of the append and prepend functions, based on my interpretation of the documentation, it seems like I would need to insert a complete image tag as an argument, triggering a new request for the image (unless the browser caches it).

Answer №1

Check out the jQuery clone documentation for more information.

This function is designed to also work with images - if an image has already been loaded by the browser, it will reuse it instead of loading it again.

UPDATE:

$( "#some_image" ).clone().appendTo( "#some_div" );

Answer №2

Most web browsers are designed to cache various types of content such as JavaScript, CSS, and images in order to improve page loading times. This means that once an image is loaded on a webpage, you can easily generate a new <img> tag using the same source path, allowing the browser to retrieve the image from its local cache instead of downloading it again.
