DataList Pagination

[solomon_13000]

I attempted to set up pagination for the datalist control. However when I click next link the next image doesn't display. Then when I click previous the first image is displayed. Did I miss something in the code?

<table border="0" width="800" bgColor="#ffffff" height="644">
        <tbody>
        <tr bgColor="#ffffff">
          <td height="173" colspan="2" bgcolor="#CCCCCC"><table width="796">
            <tr>
              <td width="303"><img src="images/logo.jpg" width="302" height="195" align="left"></td>
              <td width="497"><center><img src="images/word_bnr.jpg" width="433" height="162"></center></td>
            </tr>
          </table></td>
        </tr>
        <tr bgColor="#ffffff">
          <td height="20" colspan="2" bgcolor="#009900" align="left">
		  <span class="ex3">-:::You are currently @ the <b>GALLERY </b> section:::-</span>		  </td>
        </tr>
        <tr>
          <td rowspan="2" width="583">
		  <center>
		  <table width="569">
            <tr>
              <td height="20" width="561">&nbsp;</td>
            </tr>
            <tr>
              <td align="left">
                  <asp:DataList ID="DataList1" runat="server" RepeatColumns="3" 
                      RepeatLayout="Table">
                  <ItemTemplate>
