This is how I got my pictures posted.
On your photobucket main page by your name is a small menu arrow. Click it and go to account settings. On the menu selections across the page select album settings. Check that you want the IMG code to appear. Go back to your album pics and for every pic you want to select you will have to copy and paste that code to the work area of your posts. Using that method I did not have to use the "post an image" icon (the mountain in the little yellow box) to get results. Another tip I received was to compose your write up either in another document( I use my gmail compose option) because this allows you to save it and work it over a period of time without the problem of either closing the window inadvertently or getting fat fingered and losing it. Once finished I just copy and paste the finished product to this work space to preview it or go to the stickys above and post it temporarily with the option of nuking it.
Clear as mud?
