issue with cloned image when loading

[petvas]

I put together this example, to make it understandable:
https://jsfiddle.net/xqhsuzyn/25/

The issue is, when I clone the image, when loading the lazyloading class not change on the cloned image.

this should fix it, i was experiencing the same thing using a slider that clones the elements used for looping through them, the cloned elements would stay stuck in the lazyloading state
