Popcornbirds' hints on posting pics will help you alot.

when you copy out of photobucket the URL (which would say something like http//::www.photobucket/123456.jpg)
and you come into this message box, and see above the message box , it says

B I U SIZE FONT COLOR

and under that is a button called IMG? Click on that and simply paste that URL into there

[IMG ] http://www/photobucket/123456.jpg [ /IMG]

Then when you submit reply - the pic will appear on the thread.
Remember to make sure your pics are SMALLER tho!!!

Hope this helps
