Will images uploaded by lazy-load be indexed?

Question

Search Engine Optimization

On the page there is a list of articles and preview images for them, if you make lazy-load images so that they are loaded only when the page goes down to them, will search engines see these images?

Answer 1

What I hate lazyload, calm down the world that the user has already received megabit Internet, it’s better to shake the pictures with a good optimizer, this can bring a huge gain in the size of the pictures

Answer 2

In Canada, for example, many people have slow Internet, as in the Russian Federation. So lazy load theme. But search engines will only index the first image in poor quality.

Answer 3

Well, advisers)) They advised everything completely wrong!
Firstly, PS normally relate to this topic.
Secondly, I recommend watching the entire blog: https://www.youtube.com/user/pepelsbey/featured
Thirdly, it's better to write the code for displaying and optimizing images for yourself.
Fourthly, there is such a tool from Google: https://developers.google.com/speed/pagespeed/insights/ so if you specify a site check with lezikartinki, you can see that during testing your site, it shows them on the screen, those. perfectly downloads them from the site.
