Here is an example of optimized vs. unselected image.

Unselected images without improving WordPress

How does image optimization work?

Simply put, image optimization is done using compression technologies such as "harmful" and "useless" that help reduce the overall file size without any significant loss of quality.

What does it mean to improve images?

If you've ever received a photo improvement recommendation through your WordPress hosting support or the Speed ​​Test tool, then this means you need to reduce the size of your images.

Very basic thing to do is avoid using PNG and use JPEG or JPG wherever possible.

3. Host your images on a CDN
4. Add a lazy load plugin
If you’re using images on your site –which, I’m sure you are–, taking care of optimizing them is a must.

Multiple Image for Multiple Devices:
Wordpress does an interesting thing when you upload images into their monthly gallery directories. it makes 3 different versions of the image with dimensions and associated file sizes for different devices. ie. Desktoo, Tablet, and Phone. It then loads the appropriate image for the screen size in php. To do this second part yourself you obviously need to send the screen size back to the server in a previous page.

HTML5 offers a good alternative for the php step using media queries right in the tag, which moves the decision of which image to use to the browser. Here is a sample (note this sample uses a <picture> tag, the srcset attribute is apparently available in the image :

<picture>
<source media="(min-width:650px)" srcset="img_pink_flowers.jpg">
<source media="(min-width:465px)" srcset="img_white_flower.jpg">
<img src="img_orange_flowers.jpg" alt="Flowers" style="width:auto;">
</picture>

the
<img> tag has a similar attribure:

   <img src="hero-big.jpg" 
 srcset="hero-small.jpg 450w, hero-medium.jpg 960w, hero-big.jpg 1500w" 
 sizes="(max-width: 552px) 450px, (max-width: 1062px) 960px, 1500px"
 alt="Learnedia Hero" />

Lazy Loading:
These methods, coupled with a lazy load libray or writing your own lazy load routines (which isn't that hard) can dramatically improve your load time. The lazy load is obviously advantages when you have several images below the fold (below the viewport). I found a good article on lazy loading at https://web.dev/lazy-loading-images. It explains the concept and provides 3 methods, 2 javascript, and one new loading attribute for the <img> tag in html5 It also recomments a few lazy-load libraries, a few of which will lazy-load divs as well.

I'd wait a while on relying on the loading = "lazy" attribute for alt tags. It's relativly new, so not so older versions of browsers may not suppor it yer.
Chrome which has around 65% of the browsing community apparently started supporting it in version 77, which came out in September of 2019.
