Introduction

Actually it is not good to store Image file into Database But some time it is necessary to store it. Here I am giving solution to storing and displaying Image to Database.

Using the code

This will help you to storing and Displaying Image to Database -here Sql Server 2005.

First of all create page named AddEmployee.aspx and add repeater to it shown in source file.

The main idea is that: I am storing Image files into database directly into Binary Format. So storing it first convert it into Binary:

            SqlParameter prmFName = new SqlParameter("@_FName", txtFName.Text.Trim());
            cmdAddEmp.Parameters.Add(prmFName);
            SqlParameter prmLName = new SqlParameter("@_LName", txtLName.Text.Trim());
            cmdAddEmp.Parameters.Add(prmLName);
            int len = FIleUP.PostedFile.ContentLength;
            byte[] img = new byte[len];
            FIleUP.PostedFile.InputStream.Read(img, 0, len);
            SqlParameter prmImg = new SqlParameter("@_Image", img);
            cmdAddEmp.Parameters.Add(prmImg);
            int Status = cmdAddEmp.ExecuteNonQuery();

Now at Image viewing time:

      <td id="tdImage" runat="server">
          <asp:Image ID="img" runat="server" AlternateText='<%# Eval("FirstName") %>' ImageUrl='<%# "~/displayimage.aspx?ID="  + DataBinder.Eval(Container.DataItem,"Id") %>'  Width="50px" Height="50px"/>
      </td>

At the DisplayImage.aspx Page:

            cmdAddEmp.CommandText = "GetImage";
            cmdAddEmp.CommandType = CommandType.StoredProcedure;
            SqlParameter prmId = new SqlParameter("@_Id", Convert.ToInt32(Request.QueryString["Id"].ToString()));
            cmdAddEmp.Parameters.Add(prmId);
            byte[] byteImg = (byte[])cmdAddEmp.ExecuteScalar();
            Response.BinaryWrite(byteImg);

Response.BinaryWrite(byteImg) writes binary content of the Image and display Image.
