Photobucket isn't required on this forum - you can upload directly. On the bar above the text box where you type your post, there is an icon that, if you squint hard and have a good imagination, resembles a picture frame. Click on that, and it will have a pop-up that will give you the option of selecting a picture from your computer. Find your picture, upload, post your new post, and it should appear. If not, I think there's a thread in the admin section detailing how it works.
ETA: and scw types faster than I do.
