How to improve image loading with Gatsby and gatsby-plugin-sanity-image?

how do I achieve this same result and avoid this content jankiness (image pushing down content) in Sanity? https://css-tricks.com/do-this-to-improve-image-loading-on-your-website/
I am currently editing

Blog with Gatsby

template but so far dumbfounded on how to solve this with sanity (gatsby-image seems to do it for you). Do I modify in this file here? https://github.com/ajmalafif/afif.dev/blob/develop/web/src/lib/image-url.js
or somehow I can achieve this “lazy-loading” effect by combining both

gatsby-image

and

sanity/image-url

? https://github.com/sanity-io/gatsby-source-sanity#fluid

it seems from observation and this is anecdotal, seems like Gatsby solution do something like this to avoid the content jump https://css-tricks.com/preventing-content-reflow-from-lazy-loaded-images/
will investigate how can I figure this out for sanity on gatstby

I just published gatsby-plugin-sanity-image to provide an easy way to handle this. Use the

ImageWithPreview

version to avoid the CLS issue.

shout out to now I have a solid base to start figuring this jank-free content layout. With

Slow 3G

network on devtools I have

lqip

right away!

kinda looks this with

gatsby-image

from the markup it seems like it does something differently

You can get those thumbnails to scale up and keep your content from jumping around by putting the image in a container sized how you want, then setting the CSS on the image to

display: block; width: 100%

. Unless you are cropping the image, the LQIP should be the same aspect ratio. If you are cropping the image, you can instead set the absolute dimensions on the img element and use

object-fit: cover

on it.

again to the rescue! thanks that’s a really good pointer

is there a way to enable discussion tab on https://github.com/coreyward/gatsby-plugin-sanity-image/ since I encounter difficulties on resizing the

lqip

which I am not sure if it’s a bug (hence i dont think i should create an issue ticket) but I also want to ask how since I tried and failed

figured it out by setting the CSS for

[data-lqip]

and its all worked out now! highly recommend this plugin! Now I know how to make the site jank-free 🥳
