Depending on the exact contents of what you send, you could be opening yourself up to a world of hurt doing something like this.
Take your third image for example. What exactly are you trying to imply with it? Because it would be very easy to read that as saying that you've sabotaged something, or failed to do proper handover, and you're expecting the place to burn down (metaphorically) after you leave.
And while that might be an amusing joke to share with a few co-workers, what happens if something actually goes wrong after you've left? If a sysadmin left a company having shared that kind of image in their final email, and then the next week a load of servers go down or the company gets hit by ransomware, how does that email get interpreted by senior management? Is it just a joke, or is it an admission that you've screwed them over? Are you absolutely sure that your former co-workers, manager and senior staff in your company will see it the same way you do, especially when they're looking for someone to blame for problems who can't easily defend themselves?
If you want to share something light-hearted in your leaving email, then that's fine. But joking about stealing from your company or having sabotaged them on the way out the door is completely inappropriate, and could end very badly for you.
