Here's a nice, simple, and quick tutorial by Sweeny Todd. Another tutorial would be using Haloscreenshots.net advertised in that announcement thread. Hope this helps, and if not feel free to message me for more information.
Player has given a very good, easy to read tutorial. But Just to reasure, I'll explain personaly to you. Great you have the images on photobucket, the hard part (If you could call it that) is done. I would recommend using Imageshack. Its quicker and easier. Take the direct url for the image you want, go to you're thread and click on this symbol Insert you're Url from Photobucket or Imageshack. There you go, It does all necessary html for you. If you have any questions, Message me or Player. I feel justice has been served. :lock:
