Ajax image upload in Bitrix?

Question

1C-Bitrix

Good afternoon, how can I do ajax image loading in a slider.
There are 3 sliders on one page, each slider has 30 images (the first one has 80 images at all)
Even if you reduce the images and optimize them, you still get a huge weight. How can I do ajax upload. For example, upload 10 slides

Answer 1

This is indirectly related to 1C-Bitrix, since such a problem would be on any CMS.
You need to delve into the lazy-loading of the slider you are using.
For example, we use Swiper Slider and there are quite detailed instructions for implementing lazy loading: https://swiperjs.com/api/#lazy

Answer 2

Andrey Nikolaev Right, this is Lazy Load, otherwise, each more or less slider has an event system, in particular, a slide change event, and at this moment you can just initialize the image loading
