But… 
I don’t understand why any lazyloading plugins are not using the “unknown height” technique as I mentionned in a previous thread.
Every time I have to fix it by myself to avoid the overlapping/flashing effect on load, and specially needed on a masonry layout…
With your help, I could fix it on Kirby 2 by overriding the default kirbytag, but here with this plugin, it’s a new challenge that comes up
