Slightly odd cry for help:
My computer got some ransomware somehow, don't ask me how. It's a program that encrypts personal files and doesn't decrypt them unless I pay up. Obviously I'm not going to pay up.
As it turns out, the program killed the shadow copies (previous versions), and my last backup was a while ago.
So, I have around 60 wallpapers I downloaded straight from 4chan, specifically this board, encrypted. Luckily, I still have the post numbers of where I got them.

Does anyone know of a way to find wallpapers by post number in this board?

Thanks.

And if there isn't, please post the original and similar wallpapers of pic related, It's one of the wallpapers I managed to salvage.
