It's showing the following four thumbnails for me:
1. girl-head-10.jpeg
2. halloween-pumpkin-02.jpeg
3. flower-tattoo-11.jpeg
4. flower-cherry-blossom-02.jpeg
But the corresponding titles and links it is showing for me are:
1. Elegant Black and White Rose Illustration https://websvg.com/all-svgs/flower-rose-01-elegant-black-and...
2. Elegant Floral Heart Silhouette https://websvg.com/all-svgs/flower-designs-12-elegant-floral...
3. Playful Red Popsicle Illustration https://websvg.com/all-svgs/ice-lolly-01-playful-red-popsicl...
4. whimsical halloween house illustration https://websvg.com/all-svgs/halloween-house-04-whimsical-hal...
It seems that what happens is that the four mentioned thumbnails are there initially while the page is loading.
And that once the page finishes loading everything and running some JavaScript, it replaces the featured items.
If I reload the main page, it sometimes updates the thumbnails also but often it keeps the wrong thumbnails shown.
If I click on one of the featured thumbnails, and then navigate back to the main page, then it seems to consistently show the expected thumbnails that belong with the links in the featured row.
But doing a fresh load of the main page either by navigating to it from your HN submission link, or by reloading the page, ends up showing those initial thumbnails instead of the replaced ones most of the time.
