To update the method for posting pictures:
Hit reply, or new topic, and under where you write is a section with two tabs. One is called options, and the other is called Upload attachment. Click upload attachment. Then find your image where it says browse. You can put comments with it in the box underneath browse. Then hit "add the file", and it will be attached to your post. You can leave it like that, or click show inline which makes the image viewable immediately to all.
OR you can still do the photobucket, or other hosting site way.
