Arknights postcard event request

There's a recent Arknights anniversary event where players can draw and send each other postcards
https://5th-anniversary-card-express.arknights.global/

I'm looking for special postcards that were drawn by actual artists and pre-submitted in advance.
The number of times each player can view a postcard is limited to 30 per day, which is why I'm asking for extra help.

To quickly request a new card, login on https://5th-anniversary-card-express.arknights.global/ and then refresh https://5th-anniversary-card-express.arknights.global/api/card - the special cards have type "S", as opposed to "N" for normal player cards.

The ones I could find myself so far, in case someone wants to post, are:

Heres 15 more unique S type cards I found.

Facebook photo album with 148 S type cards. Unfortunately, they got converted from pngs to jpgs. And the original source links aren't posted.

My estimate of number of possible static image links. Should be possible to brute force, no?
= 38^8 = >4.35e12
from 38 possible characters(26 letters, 10 numbers, -,_) and 8 character length

Edit: All my new cards will be placed together with the old cards in the expand block.

At 1/ms that'd still take over a century. And there appear to be capital and lowercase leters.

Opps. Ok i underestimated 8 character passwords.

https://5th-anniversary-card-express.arknights.global/api/card is now returning "401 Unauthorized" message.

I created pool #24822, for the postcards.
Would it be a good idea to add the media asset numbers to the pool description? Most of them haven't been uploaded.

The event has ended, but my old cookie seems to still have the access to api. I updated the original post with all the cards I have.

There is also a third-party source which mostly gives pixel-perfect duplicates to the official source for cards I managed to get.
