UpdatePanel Image from array - asp.net

Question

Actually I wish to round corner the Image and then display it in updatePanel...
Without roundcorner functions it's working fine...But when I run the functions for round corner image, its giving File Not Found Error()
My Codes
protected void Timer1_Tick(object sender, EventArgs e)
{
NameValueCollection MyImgList = new NameValueCollection();
MyImgList.Add("Img1", "~/MyImages/Picture1.jpg");
MyImgList.Add("Img2", "~/MyImages/Picture2.jpg");
MyImgList.Add("img3", "~/MyImages/Picture3.jpg");
Random Rnd = new Random();
int Indx = Rnd.Next(0, 4);
path = MyImgList[Indx].ToString();
//LtrImg.Text = "<img src='" + Page.ResolveUrl(path) + "' alt=''/>";
using (System.Drawing.Image imgin = System.Drawing.Image.FromFile(path))
{
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(imgin.Width, imgin.Height);
Graphics g = Graphics.FromImage(bitmap);
g.Clear(Color.White);
Brush brush = new System.Drawing.TextureBrush(imgin);
FillRoundedRectangle(g, new Rectangle(0, 0, imgin.Width, imgin.Height), roundedDia, brush);
// done with drawing dispose graphics object.
g.Dispose();
// Stream Image to client.
Response.Clear();
Response.ContentType = "image/pjpeg";
bitmap.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
Response.End();
// dispose bitmap object.
bitmap.Dispose(); /* May be Here */
}
LtrImg.Text = "<img src='" + Page.ResolveUrl(path) + "' alt=''/>";
}
Thanks for the guidances..

Anyhow I succeeded by the following way..
protected void Timer1_Tick(object sender, EventArgs e)
{ NameValueCollection MyImgList = new NameValueCollection();
MyImgList.Add("MyImage1", "~/MyImages/Picture1.jpg");
MyImgList.Add("MyImage2", "~/MyImages/Picture2.jpg");
MyImgList.Add("MyImage3", "~/MyImages/Picture3.jpg");
Random Rnd = new Random();
int Indx = Rnd.Next(0, 4);
Session["ImgId"] = Indx.ToString();
Image1.ImageUrl = "ImgWebForm.aspx?ImgId="+Indx.ToString().Trim();
}
and then
ImgWebForm.aspx Page_Load()
{
string ImgFileId = Session["ImgId"].ToString();
switch (ImgFileId)
{
case "1":
path = Server.MapPath("~/MyImages/Picture1.jpg");
break;
case "2":
path = Server.MapPath("~/MyImages/Picture2.jpg");
break;
case "3":
path = Server.MapPath("~/MyImages/Picture3.jpg");
break;
}
int roundedDia = 50;
using (System.Drawing.Image imgin = System.Drawing.Image.FromFile(path))
{
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(imgin.Width, imgin.Height);
Graphics g = Graphics.FromImage(bitmap);
g.Clear(Color.White);
Brush brush = new System.Drawing.TextureBrush(imgin);
FillRoundedRectangle(g, new Rectangle(0, 0, imgin.Width, imgin.Height), roundedDia, brush);
// done with drawing dispose graphics object.
g.Dispose();
// Stream Image to client.
Response.Clear();
Response.ContentType = "image/pjpeg";
bitmap.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
Response.End();
// dispose bitmap object.
bitmap.Dispose();
}
public static void FillRoundedRectangle(Graphics g, Rectangle r, int d, Brush b)
{
// anti alias distorts fill so remove it.
System.Drawing.Drawing2D.SmoothingMode mode = g.SmoothingMode;
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;
g.FillPie(b, r.X, r.Y, d, d, 180, 90);
g.FillPie(b, r.X + r.Width - d, r.Y, d, d, 270, 90);
g.FillPie(b, r.X, r.Y + r.Height - d, d, d, 90, 90);
g.FillPie(b, r.X + r.Width - d, r.Y + r.Height - d, d, d, 0, 90);
g.FillRectangle(b, r.X + d / 2, r.Y, r.Width - d, d / 2);
g.FillRectangle(b, r.X, r.Y + d / 2, r.Width, r.Height - d);
g.FillRectangle(b, r.X + d / 2, r.Y + r.Height - d / 2, r.Width - d, d / 2);
g.SmoothingMode = mode;
}
Let it be useful to someoneelse like me..
Thankyou ...
