Setting a custom load screen?

I’ve seen people with custom load screens when joining various servers. I was wondering how I’d set one up for my TTT one? I’m not sure if it’s a simple .jpg or html document, or what to size to make it, or how’d implement it in. If it makes a difference, we’re using the Evolve admin mod.

Any help is appreciated!

As for the actual loading screen, you’re going to need a web host, and basic knowledge in HTML and PHP, if you plan on having it change according to the player connecting.
