BlurHash: Algorithm to generate compact representation of an image placeholder

any ideas how this would impact on SEO/Pagespeed? if you are doubling the amount of pictures being loaded, albeit a tiny placeholder for a thumbnail - not from a size perspective, but from a network perspective surely this would double the amount of image fetches

The whole idea here is that you do not need to fetch an extra image. The image is generated in code on the client side from the short string. So there is no network connection needed, and the placeholder is there instantly.

then there must be some computational cost for the client

Of course. The cost is fairly small, though, since you only need to generate very tiny thumbnails, and can then just scale them up.
