Below is my code that works the way it is written... it pulls the blob image out of the database and displays it on a webpage. But what if I want it to display in a control on that webpage? Right now I have 2 aspx pages.

The first one just gives the second on the ID.
<a href="WebForm1.aspx?ID=70">Go</a>


The second one displays the image. But I need to put other information on this page so I need the image to go into a placeholder. I just put an <img> tag on this page. How do I get the output from the below code to go into that img tag?

<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<% @Import Namespace="System.IO" %>
<% @ Import Namespace="System.Data" %>
<% @ Import Namespace="System.Data.SqlClient" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        WebForm1

    </div>
    <div>
        <script runat="server">
           
            Private Overloads Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

                Dim sSQL As String = "SELECT ThumbNailPhoto FROM Production.ProductPhoto WHERE ProductPhotoID='" & Request.QueryString("ID") & "'"
                Dim myReader2 As SqlDataReader
                Dim myConnection2 As SqlConnection = New SqlConnection
                myConnection2.ConnectionString = ConfigurationManager.ConnectionStrings("FT_Data").ConnectionString
                Dim myCommand2 As SqlCommand = New SqlCommand()
               
                With myCommand2
                    .CommandText = sSQL
                    .CommandType = CommandType.Text
                    .Connection = myConnection2
                    .Connection.Open()
                    myReader2 = .ExecuteReader(CommandBehavior.CloseConnection)
                End With

                While myReader2.Read
                    Response.BinaryWrite(myReader2("ThumbNailPhoto"))
                End While

                myCommand2.Dispose()
                myConnection2.Dispose()

            End Sub

        </script>

    <div style="background-color: #000000; border: medium solid #C0C0C0">
        <img alt="" id="myimage" name="myimage" src="" runat="server"/>
    </div>
       

    </div>
    </form>
</body>
</html>

Hello,

You have to put one literal control for getting image, and into coding side, you have to write like this.

Get the data into DataReader

While Reader.Read

literal1.Text = "<img src='../Images/' " & Reader.Item("ImageFiledName") & " height='' width='' />"

End While

Place asp:image control in your aspx page and call a HTTPHandler by passing id of the image as a paramerter. Implement database accessing business logic in  the HTTP handler.
