how to fetch binary data from sqlserver image field and then convert into an image

Do the following steps:

1) Create one blank aspx page
2) Assign panel as Panel1.BackImageUrl= url of that new page
3) Write code In that page that reads image bytes from database table binary field and write to that page using page.Response.BinaryWrite(bytes())

The panel will display the image rendered on that page.

In aspx i addded an image control

<asp:image runat="server" id="ImageViewer" imageurl="~/Handler1.ashx" xmlns:asp="#unknown" />

Then in code behind

Imports System.IO
Imports System.Drawing
Imports System.Data.SqlClient

Public Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim Con As New SqlConnection("data source=local;initial catalog=MYDB;User id=santhosh.kumar;password=pass@123")
        Dim cmd As New SqlCommand("select  cropImage from serverdocument where document_id=10217533", Con)
        Dim data() As Byte
        Con.Open()
        data = cmd.ExecuteScalar()

        Session("ImageBytes") = data
       
    End Sub

   
End Class

Then i added new Generic handler.

Imports System.Web
Imports System.Web.Services

Public Class Handler1
    Implements System.Web.IHttpHandler, System.Web.SessionState.IRequiresSessionState

    Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

        If (context.Session("ImageBytes")) IsNot Nothing Then
            Dim image As Byte() = DirectCast(context.Session("ImageBytes"), Byte())
            context.Response.ContentType = "image/JPEG"
            context.Response.BinaryWrite(image)
        End If

    End Sub

    ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
        Get
            Return False
        End Get
    End Property

End Class

Now run. It will display the image.
