How to upload images from external url after page is loaded ?

Hello, In Laravel 5.8 / vuejs 2.6 / Bootstrap 4.3 app I make search by url on remote server and any returned row can have img_ref field and if this field is not empty I need to show in listing of items. Any Page has 20 items and 4-5 items are visible on one screen page. I do not want to upload all these image at once, as it can take long time. If there is a possibility to upload all images after page is uploaded and user can view content of the page?

Seems such teqnology called “Lazy-load”? Please give ref/example what can I use in this case?

Thanks!
