No bother. If anything's a bother, it's getting used to the new photobucket layout.
To begin with, you have to use click the "use rich formatting" option here at FSM, then you have to have a second browser window open to your photobucket. Hover your cursor over the photo you want, and a little cogwheel icon should appear in the upper left hand corner. This should open a box with several choices, including "get media links." This is what you want.
Copy the option called "direct link." Sometimes you can do this with a left click, but only when the little "finger pointing" icon appears. It doesn't always. A glitch, I think. Then, you'd have to highlight and copy.
After that, return to the FSM site. In the menu box, you'll see a photo icon in the lower row, about the middle. Click this and a window will open. Paste the copied "direct link" where indicated, and click "insert."
Your photo should come through, and you should be able to see it almost immediately in your posting, before you hit the "post" button.
Sound complicated, until you use it a few times. I don't like the new format for photobucket very well either, but I've stuck to it anyhow.
Give it a try, and good luck. As Admiral Kirk once said to Lt. Saavik: "We learn by doing."
And sometimes it takes a lot of doing!
