How to make a Minecraft server picture?

Most servers I've seen have pictures next to their server sorta what it's called, like TheHive is a picture of a bee. How do I actually make my server, (FireBenders) have one of those?

It is very simple.

1. Make a picture that is 64 x 64 (pixels) or get one from Google.
2. Customize it to your liking.
3. Save it as "server-icon" and make sure it's a.png file.
4. Drag and drop it to the root of your minecraft folder. (Same folder where you put your craftbukkit.jar)

If this doesn't work please message me.
