Well, look no further. I have finally found a free hosting provider for those of you that don't have your own, so you can host your own collection of randomly rotating avatars, like the one I'm sporting.
Thus, inspiration drove me to write a complete tutorial on even the most minimal things of getting, configuring, setting up, and using my Random Avatar Script of Doom™.
Beware though, as it's a bit of a lengthy read, for it covers every single aspect of the script, including, but not limited to, configuration, signing up for and setting up an account at the hosting provider, and testing each and every function of the script, among other things.
Enjoy, and drop any comments, feedback, questions, complaints, cheese, wine, boobs and beamsabers here.
