PHP Code:

 if (file_exists($file_name)) { 
                    echo"
                            <table width=414 border=0 cellpadding=0 cellspacing=0 align=center>
                               <tr>
                                <td width=414 height=13 align=center valign=top class=main-table><strong>IMAGES UPLOAD </strong></td>
                              </tr>
                              <tr>
                                <td height=100% bgcolor=#333333></td>
                              </tr>
                              <tr>
                                <td height=22 align=center valign=top class=main-table>
                                File already exists, Please change the filename or try another one.
                                </td>
                              </tr>
                                <tr>
                                <td height=100% bgcolor=#333333></td>
