Email Attachments

Question

i am having images in the database table. i am getting the file in the front end for the code,

SqlCommand cmd = new SqlCommand("select * from Tbl_VisitorRequestDetails where VisitorId = 1212312313",con);
SqlDataReader dr = cmd.ExecuteReader();
while(dr.Read())
{
Response.BinaryWrite((byte[])dr["PersonImage"]);
}


The above one writes the image in the form.

But i want the file(image) to get attached in to the Email attachments, without saving the image as file and then attaching.
I want the file(image) to be attached directly to the Email-attachments.

Help me in C#.
Thanks.
