Thanks for asking. It's funny how for HR so many images really aren't HR. I've found that you can play with URLs from content to providers to sometimes get higher quality versions than intended. Here's an example for the swimsuit pics:
https:// swimsuit period si period com/.image/c_limit%2Ccs_srgb%2Cq_auto:good%2Cw_1281/MTgyNDUyMzIxNDQyMDc5ODc1/x163584_tk1_00301wmweb.webp
If you replace "c_limit%2Ccs_srgb%2Cq_auto:good%2Cw_1281"
with "c_limit%2Ccs_srgb%2Cq_auto:best%2Cw_10000" and "wmweb.webp" with "wmweb.png" it should serve the best quality of the image available to the public from the server.
Frustratingly these shots are at a even higher res somewhere on Getty Images, but can't even buy them for the usual $499, not that I would but maybe some Saudi dude could.
