I try to explain, but my primary language is Dutch, so I don't know if you can understand my english explanation.

The problem in your post was, that you used the URL of the entire page, instead of the URL of the picture.
I pasted the URL from your post in the address-bar of my browser, and went to the page where the picture was on.
I right-clicked on the picture, and choose in the context-menu that appeared 'save URL of picture' (or something like that... My browser is Dutch...)

Then you type
[ img ] URL of img [ / img ]
without the spaces. The URL of the picture normally ends with '.jpg' or sometimes '.png'

In your case for the first pic is was
[ img ] http://i1366.photobucket.com/albums/r775/ldarlener/Linda2013-04-26185749_zps7a54ce54.jpg [ / img ]

I have never posted a pic. But I'm going to try. Before April 2013 at our local Relay For Life. Yes I WILL do anything for Relay. Even dressing in all purple http://s1366.photobucket.com/user/ldarlener/media/Linda2013-04-26185749_zps7a54ce54.jpg.html?sort=3&o=1
