[tech]images/content inclusion

[Nyro]

Seems I'm the first to post, I hope it does worth it.
I was wandering on the internet wondering if and how it would be possible to insert custom images, like a guild banner a start (even if it's not necessarily the world best add-on, I agree on that).
Now that it's been posted I can continue my research in peace, i guess.
Thanks in advance.
