Jenn I often link to pics on my facebook...
When on facebook right click on the piccy you want to appear in your post on here... select properties and copy the image url..
Then when you are writing a post paste the image url - highlight it all and then click on the little insert image button above the text box where you type.. its the second one along in the little row of buttons above the smilies.
Then when you press post the image will appear in your post ...
like this one
The same might also work for the dancing hippo.. which to me always has looked mighty dodgy.
