Hi.
first u drag file from html controls id as PersonImage put one asp web button in that click event write this-

C#

Int64 intImageSize;
string strImageType;
Stream ImageStream;
//  Gets the Size of the Image
intImageSize = PersonImage.PostedFile.ContentLength;

strImageType = PersonImage.PostedFile.ContentType;
//  Reads the Image
ImageStream = PersonImage.PostedFile.InputStream;

int intStatus;
intStatus = ImageStream.Read(ImageContent, 0, intImageSize);
SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"));
SqlCommand myCommand = new SqlCommand("sp_person_isp", myConnection);
//  Mark the Command as a SPROC
myCommand.CommandType = CommandType.StoredProcedure;
SqlParameter prmPersonImage = new SqlParameter("@PersonImage", SqlDbType.Image);
prmPersonImage.Value = ImageContent;
myCommand.Parameters.Add(prmPersonImage);
SqlParameter prmPersonImageType = new SqlParameter("@PersonImageType", SqlDbType.VarChar, 255);
prmPersonImageType.Value = strImageType;
myCommand.Parameters.Add(prmPersonImageType);
try {
   myConnection.Open();
   myCommand.ExecuteNonQuery();
   myConnection.Close();
   Response.Write("New person successfully added!");

If it is that urgent, I will look it up at Google[^].

This has been done so many times before and there are tons of example on Google. Look at the links below:

It's not a brilliant idea to necessarily store images in a DB - they tend to be quite large and can both clog up the DB and cause a lot of bandwidth to be used - particularly if the DB server is not the same computer as your webserver. In that case the image data has to transfer from the DB server to teh webserver before teh web server can serve it to the client. This wastes time, and traffic.
If they are tiny images (avatars maybe, or thumbnails) then it's a good idea, but if they are large images then much, much less so. A better solution is to store them under temporary names, and store the full path to that temporary name in the db.

There is a tip here which may help: A generic Image-From-DB class for ASP.NET[^]

There are many solutions.

First look at:
http://www.redmondpie.com/inserting-in-and-retrieving-image-from-sql-server-database-using-c/[^]

and

Storing and Retrieving Images from SQL Server Using Strored Procedures and C#.net[^]

To display in a webpage you could implement something I suggested to another member a little while ago.

Return Image From asp.net web service and consume in javascript[^]

Store image in database and then retrieve it using c#
