A simple solution that I use on the kinoplay.me website to upload images after the page loads.
Add a link to the image in the data-src attribute in the
![]()
tag
And in the src = "" attribute, add a link to the stub, this script will download posters after the page is fully loaded, this will look good for users since the page performs a full load much faster
Tag example:
img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://kinoplay.me/uploads/posts/2020-04/1586098822_300x450.jpeg"/>
