Hi. Once you learn the trick, Photobucket is really easy. Well, unless your talking about Photobucket
from your phone, then you can ignore me.
On PB, you can hover your mouse over a picture, and then a menu appears. The bottom option says "IMG code". Click in the box next to that, and it should automatically copy the text for you (if not, you can copy it yourself). You then paste that directly into a post here, and it has the right syntax for an embedded image.
If you quote my post, you'll see the type of code that I'm talking about below this.
