Thanks @maoznir
I’m only going by the documented behaviour here: https://cloudinary.com/documentation/react_image_manipulation#image_placeholders
I thought I’d comment my support for this as well, as I’m experiencing the exact same issue as @taijuten and the way he described it is consistent with the behaviour I’m seeing on my project.
On a product category page for an online store, all the image placeholders on the page should be loaded eagerly creating a “blurred” placeholder, then “blurred up” lazily to the target image.
What actually happens is the placeholder itself will be lazily loaded on scroll, causing a brief flash of whitespace, followed by a brief flash of blurred placeholder image, then followed by the target image load.
