Under the image in your Album at photobucket you'll see an img code. Highlight then right click and Copy and paste it over here in the reply, then change the capital IMG to small case img.

Or actually pull up the image, right click, go to properties and you'll see a URL code, highlight, right click, andcopy this, pull up the add image icon here in the reply, and paste it. That's how I got your image. But the first way is easier to me.
