I put the word stuff here on the post where ever I want the buttons, then click the use html, highlight the word stuff here, click on the html version in photobucket and then on your post click ctrl v.
If you're really unsure about it, use a post, do it how you'd do a tag, just click the html button at the bottom here and press ctrl v to get the html on the post. When you look the button will be on the post, put all your buttons on posts then just copy and paste them onto the webset from the post.........you can do that, just not from photobucket.
Failing all that, give me your access to the buttons on your account (i think you can do that...not sure) and I'll do it lol.
Sorry if not clear......If you need it clearer just ask.
