Topic: multiple galleries side by side

using frontpage, I am trying to put 3 galleries next to each other, one left, one center, and one right. putting the script code in only makes the viewer put it in the center of the html page. Can anyone tell me how to left justify the first and center the the second and so on.

here is the code i am using

<p align="left">&nbsp;<div id="flashcontent" style="width: 406; height: 19">
  <p align="left">SimpleViewer requires JavaScript and the Flash Player. <a href="">Get Flash.</a></div>
        <script type="text/javascript">        var fo = new SWFObject("viewer.swf", "viewer", "480", "550", "8", "#000000");        fo.write("flashcontent");
