Sure! But I can only help out with getting the files themselves, as I've never used TamperMonkey. First go to https://tampermonkey.net, and download the one for your specific platform. Then, after it's installed, go to the GitHub link above your comment, and download the "Imgflip Plus-1.0 (1).user.js" file. From there, I'm sorry, but you're on your own.
