Thank you. I went through and did a trial/error to figure out which center it was, and have it working now.
To change the Poster name to align to left:
FIND:
<td class="{$Style['tddetails']}" align="center" valign="top">
CHANGE TO:
<td class="{$Style['tddetails']}" align="left" valign="top">
To change the Photo Detail description area
FIND:
<div align="center"><span class="{$Style['small']}"><br />$desc</span></div>
CHANGE TO:
<div align="left"><span class="{$Style['small']}"><br />$desc</span></div>
