Diesel....looks like you got part way, with the account. The rest is easy.
Below your picture(s) in PhotoBucket, you'll see links. Left click on the bottom one ( IMG code), it will turn blue. Right click and a small box pops up, choose copy.
Then in your post where you want the picture, right click, in the small box choose paste.
Done !
Remember to start a new line for each picture, so they do not end up side by each ! Also do not type more words at the end of the link. Start a new line.
