and all we would have to do is just click the link?

That's correct. The image needs to be loaded (won't probably even display anything) to execute its payload.

is there anyway to know if i have their malware on my pc?

Malwarebytes, maybe?

I'm not using Windows outside a VM, so I'm not too concerned about it since I can restore a clean snapshot in seconds.

If you're talking about 0-day threats and high sophistication adversaries, then no. Malwarebytes isn't gunna do anything.

Unfortunately, if you're dealing w/ an adversary with this level of sophistication, unless you're an expert in digital forensics and reverse engineering software... then nothing you can do. If you think you're infected, reinstall your OS and practice safe computing moving forward.
