Lazy loading tip

[Hisashi]

Hello

I'm using two elements to cause fast page loading.

<img data-src="{file='$file' extension='cms_Records'}" loading="lazy" style="height: auto;" class="ipsImage MangaImage" alt="...">

data-src and loading="lazy"

My doubt is, does one thing cancel out the other or can maintain these two elements?

I have a manga reader, the images are heavy.
