So this is for anyone who wants to add pictures to their post through photobucket, but it can also apply to other hosting site.
1.Make an account with photobucket. Its not hard, and if you're super lazy I think you can just connect it to FB.
2. Upload the photo(s) you wish to put in your thread onto photobucket.
3.Go to the picture that you want to put into your thread. Look for the img code(the red box) and copy that.
4.Paste just the img code into the message part or the reply part of a thread. Once you check the rest of the post for any errors or crap, click either the preview post or submit new post button to see if it works.
If everything works right, your picture should pop up and BAM! your posting pictures now.
