In the img of your html, add the following: id="thisone"
(Note that 'thisone' can be anything you want, like 'herbert' or 'something' or 'yahoo' or 'whatever'.)
Next, up top, between < head > and < / head > in your html, place something like this:
< style type="text/css" >
img#thisone { float:right; margin:1em; }
</ style >
That'll move your image to the right side, and make sure it gets a little padding so's it doesn't go TOO far to the right, plus gets a little padding so stuff doesn't cram up next to it.
Later, if you change your mind and want it back to the left, just change 'float:right'
to 'float:left'
