<script>
	// 	for first time you will get all image from this load from internet
	// 	its normal because no image cached before
	// 	so if you wanna see its working, try it will with change looping or something reactivity will work
	import { lazyimage } from '@svelte-bin/image';
	const placeholder = 'https://media3.giphy.com/media/3oEjI6SIIHBdRxXI40/200.gif';
	// 	try change size and see image load from internet or cache
	const src = 'https://random.imagecdn.app/200/250';
	const alt = 'Random Image';

	let onlyForLooping = [];
	for (let i = 0; i < 100; i++) {
		onlyForLooping[onlyForLooping.length] = '';
	}
</script>

<!-- No Cache -->
<img
	use:lazyimage={{ cache: false }}
	src={placeholder}
	data-src={src}
	{alt}
	on:cacheload={() => console.log('load from cache')}
	on:imgload={() => console.log('Load from internet')}
/>

<!--
Check console when scrolling. if your brwoser support intersection observer
and you enable cache,another image with same url (cached) will use instead of load from internet
-->
{#each onlyForLooping as _}
	<!-- With Cache  -->
	<img
		use:lazyimage
		src={placeholder}
		data-src={src}
		{alt}
		on:cacheload={() => console.log('load from cache')}
		on:imgload={() => console.log('Load from internet')}
	/>
