something I can actually help you with
you can either A) select the pic on your photobucket page, scroll down, click the option of generate img and html tags, and select the way you want to post your image (I generally use clickable thumbs because I hate posting huge pics on a board) or
B) copy the URL of your pic and type in (substitute square parens for my round ones) (url)now paste in the image location then type in(/url)
give it a shot... postings free and you can always delete it if it doesn't work out.
If that doesn't make sense tap 'reply with quote' to this post and you'll see how it works.
or clickable thumb
oops I just repeated what Soul said.. sorry.
