Mac ox x theme help please

[Fatcat]

My gallery is located at http://www.fatcatville.com/gallery/

Below the admin menu there is some sort of background image or something that I would like to get rid of.  I can't find where this is coming from.  It doesn't show up on all the pages.  Any idea how this is showing up?  Thanks for any help with this.

Looks like it is due to this empty cell:
<td class="tableh1a"><img src="themes/mac_ox_x/images/tableh1a_bg_left.gif"></td>

It has something to do with this in the theme.php:

Code Select Expand

<!-- Start standard table -->

<table align="center" width="$width" cellspacing="0" cellpadding="0">

  <tr>

   <td background="themes/mac_ox_x/images/main_table_r1_c1b.gif" valign="top"><img name="main_table_r1_c1" src="themes/mac_ox_x/images/main_table_r1_c1.gif" border="0" id="main_table_r1_c1" alt="" /></td>

        <td width="100%"><table width="100%" cellspacing="1" cellpadding="0" class="maintableb">



EOT;

    } else {

        echo <<<EOT



<!-- Start standard table -->

<table align="center" width="$width" cellspacing="0" cellpadding="0">

  <tr>

   <td background="themes/mac_ox_x/images/main_table_r1_c1b.gif" valign="top"><img name="main_table_r1_c1" src="themes/mac_ox_x/images/main_table_r1_c1.gif" border="0" id="main_table_r1_c1" alt="" /></td>

        <td width="100%"><table width="100%" cellspacing="1" cellpadding="0" class="maintable">



EOT;
I am wondering what this is?
