That happens when you have container (i.e. read more) that unveils content on click.
Right now - image would be loaded. Even though it's not visible due to being hidden within parent.
Sample code:
<div class="show_more"><a class="show-more"> Read more …</a> -> clicking makes next div visible
<div class="content-hide">
// image here
</div></div>
Firstly, thanks for taking the time to develop and share.
I am attempting to implement io-lazyload on a WordPress site. I can see that images are only downloaded by the browser as they come into view (as expected), however the image displayed to the user does not ever change from the low-res placeholder (in this case, an SVG).

Hi
Can you please publish your code as npm package?
Thanks
When using IOlazy with IntersectionObserver
Polyfill in Safari 11 the Polyfill’s _parseRootMargin
method crashes with a TypeError e.split is not a function. (In 'e.split(/\s+/)', 'e.split' is undefined)
.
This is caused by IOlazy passing rootMargin
as Array which can not work with the polyfill.
Please update IOlazy class to pass rootMargin
as String which is – as far as I can tell – expected in the spec, too.
some super old things here need updated. Mainly gulp and babel
Possibly using some other data tag like data-bg?
I used dataset
https://github.com/cdowdy/io-lazyload/blob/master/src/js/iolazy.js#L48-L54
and this will choke in IE 10.. so.. do i use getAttribute or just leave it since they are no longer supported by Microsoft.. hmm

or should I just make a mention of it in the demo page/readme?
