In HTML, do something like this.
Put the table and the pic you want centered between the <center></center> tags, and put "align=right" in the <table> tag. Be sure to put the table in first... otherwise the table will be positioned below the pic instead of directly to the right.
<center>
<table align=right>
<tr>
<td>
I'm in a table.
</td>
</tr>
</table>
<img src="pic.jpg">
</center>
There are other ways (namely using CSS) to do this, but I was going for a simple approach.
HTH!
