Ok. This is another newbie boo-boo.
I found the answer to my own question.
I was so engrossed in looking at the html code and the editor window in wordpress that I did not scroll down to look at my post preview window to see the command working all this while.
But anyway, I think there is a slight error to the picture example given in:
Wrapping Text Around Images « WordPress Codex
for:
The leaf image should be on the right with the text wrapped around.
Sorry if I caused any inconvenience in creating this thread.
