Hm.Well, I can drag the thumbnail over, open Insert/Edit Image on it, then go to the Link tab, and copy/paste the Photobucket "URL" field from the Photobucket widget. Copy/paste isn't very convenient from iPad though.
I think the best thing to do is to make a public Photobucket album for now, and just post the link to the album? And then I'll try to work out something better soon. Sorry!
