You're lucky to have me as a friend, people I asked wouldn't tell me,
so I had to go fish it out in Cypher's stuff :I
Okay, so basically what you have to do is do some text, then insert the code below:
<img src="URL" align="right"/> (it can also be left if you want, but never try center)
And make sure it's in the middle of text, like so:
blah blah blah <img src="URL" align="right"/> blah blah blah
Hope I helped!
