图片轮转图片显示个数问题

我想显示6个图片，数据库中不超过6条数据时可以正常显示，超过6条出现问题，（如7条，则最新第一个图片显示不出来），一下是代码
public void BindPic()
{
try
{
string sql1 = "select top 6 imgName,url from product_resident order by id desc";
db.GetConnection();
//SqlCommand cmd = new SqlCommand("select imgName,url from product_resident order by id desc ", con);
//SqlCommand cmdNum = new SqlCommand("select count(ID) HAO from NewImage", con);
string sql2 = "select count(id) HAO from product_resident";
//SqlDataReader readNum = cmdNum.ExecuteReader();
SqlDataReader readNum = db.GetDataReader(sql2);
readNum.Read();
int Number = (Convert.ToInt32(readNum.GetValue(0).ToString()));
int changeNum = 0;
if (Number >= 6)
{
changeNum = 6;
}
else
{
changeNum = Number;
}

readNum.Close();
SqlDataReader read = db.GetDataReader(sql1);
string[] imgUrl = new string[6];
//string[] imgtext = new string[6];
string[] imgLink = new string[6];
int count = 0;
//string str = "";
string pics = "";
string links = "";
//string texts = "";
int focus_width = 165;
int focus_height = 205;
//int text_height = 18;
int swf_height = focus_height;

while (read.Read())
{
imgUrl[count] = read.GetValue(0).ToString();
//imgtext[count] = read.GetValue(1).ToString();
imgLink[count] = read.GetValue(1).ToString();
//str += imgUrl[count] + "escape(" + imgLink[count] + ")";
if (count < (changeNum-1))
{
pics += imgUrl[count] + "|";
links += imgLink[count] + "|";
//texts += imgtext[count] + "|";
}
if (count >= (changeNum - 1))
{
pics += imgUrl[count];
links += imgLink[count];
//texts += imgtext[count];
}
count++;

}
read.Close();
//con.Close();
if (Number != 0)
//if (count != 0)
{
this.TD1.InnerHtml = "<script type='text/javascript'>" +
"document.write('<object classid=clsid:d27cdb6e-ae6d-11cf-96b8-444553540000 codebase=http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0 width=" + focus_width + " height=" + swf_height + ">');" +
