Lazy Blur Images is a light component that allows developers to implement an async image charge in their websites when they are in the visible area of the user
You can view a example of this library from here
Lazy Blur Images works with base64 images to show a light preview while the real image is downloaded in the background, the image will be downloaded after the "load" event if it is in the visible area, by default the Intersection Observer API is used to detect if the image is in the visible area
You can get and manipulate a placeholder from the official (and free) Placeholder Studio for this package
We need to get our base64 small image from Placeholder Studio
