How to lazy load images in joomla?

Question

Joomla

Hello. Created an ad site on joomla. The site is designed for an area with low quality of communication. Everything seems to be working. Now I need to make it so that the images do not load immediately, but instead of images there is something like a button on an empty square. How does is called? Are there ready-made solutions in joomla? Plugins, etc.
