in database table is thier . in that table fields are photoid , photoname,photo... i want display ..

Answer / .....

initially while inserting image into database take the
database field in oracle as BLOB in sql as image

during insertion convert the image file into bytes and
insert it into the database

during the display of image in datagrid take a image
template and display the converted values
sample code to get the image:
public byte[] spic(string cm,int id)
{
con = new OracleConnection(cm);
OracleCommand cmd = new OracleCommand("select
photo from kir_image where eid= "+id +" ", con);
con.Open();
byte[] img = (byte[])cmd.ExecuteScalar();
con.Close();
return img;
}

use Response.BinaryWrite to display the image
