    [2005] Storing images into data base...plz help me

    i m working on an application whisch purpose is to store images into data base.
    i m using sql script for this purpose and sql script is given below.


    CREATE TABLE [dbo].[Albums] (
    [id] [int] IDENTITY (1, 1) NOT NULL ,
    [name] [varchar] (20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
    [desc] [varchar] (200) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
    ) ON [PRIMARY]
    GO



    CREATE TABLE [dbo].[Photos] (
    [id] [int] IDENTITY (1, 1) NOT NULL ,
    [name] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
    [desc] [varchar] (200) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
    [album_id] [int] NOT NULL ,
    [photo] [image] NULL
    ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
    GO



    CREATE PROCEDURE sp_GetPhotoAlbums AS
    SELECT Albums.[id] AS AlbumID, Albums.[name] AS Album, Albums.[desc] AS Album_Desc,
    Photos.[id] AS PhotoID, Photos.[name] AS Photo, Photos.photo, Photos.[desc] AS Photo_Desc
    FROM Albums INNER JOIN
    Photos ON Albums.[id] = Photos.album_id
    ORDER BY Albums.[id]

    GO

    CREATE PROCEDURE sp_InsertPhoto
    @name AS VARCHAR(50),
    @image AS IMAGE,
    @album AS INT
    AS

    INSERT INTO Photos ([name], photo, album_id)
    VALUES (@name, @image, @album)

    RETURN @@identity

    GO

    CREATE PROCEDURE sp_NewAlbum
    @name AS VARCHAR(20)
    AS

    INSERT INTO Albums ([name])
    VALUES (@name)

    RETURN @@identity
    GO

    Select * from Photos

    when I run my application, it gives an error at the start
    The error is "couldn't find stored procedure'sp_GetPhotoAlbums'.
    Then I ok this msg and add photos in to the data base.
    when I close my application and run it again then there is no photos in to the database
    how can I solve this problem.
    secondly my apllication shows photo in to the picture box very small and quality of image is not so goood.
    i want to show the image big like the size of pic box and quality should be improved
    for this purpose i m using this function

    Private Sub DrawToScale(ByVal bmp As Image)
    ' The client rectangle
    Dim rc As Rectangle = PictureBox.ClientRectangle


    Dim size As New SizeF(bmp.Width / bmp.HorizontalResolution, bmp.Height / bmp.VerticalResolution)
    Dim fScale As Single = Math.Min(rc.Width / size.Width, rc.Height / size.Height)

    size.Width *= fScale
    size.Height *= fScale


    ' Create a new bitmap of the proper size for the existing bitmap
    ' and assign it to the picture box
    PictureBox1.SizeMode = PictureBoxSizeMode.AutoSize
    PictureBox1.Image = New Bitmap(bmp, size.ToSize())
    End Sub
    i m calling this function in to the following function
    Private Sub ShowThumbnail(ByVal item As TreeItem)
    Try
    ' Create a command to select the selected photo
    Dim strCmd As String = [String].Format("SELECT photo FROM Photos WHERE id = {0}", item.Id)
    Dim cmd As New SqlCommand(strCmd, SqlConn)



    ' Get bytes return from stored proc
    Dim b As Byte() = CType(cmd.ExecuteScalar(), Byte())
    If b.Length > 0 Then
    ' Open a stream for the image and write the bytes into it
    Dim stream As New System.IO.MemoryStream(b, True)
    stream.Write(b, 0, b.Length)

    ' Draw photo to scale of picturebox
    DrawToScale(New Bitmap(stream))

    ' Close the stream and delete the temp file
    stream.Close()
    End If
    Catch e As Exception
    MessageBox.Show(e.Message)
    End Try

    i m calling above function in to the tree view event AfterSelect
    Private Sub treeAlbum_AfterSelect(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles treeAlbum.AfterSelect
    Try

    Dim item As TreeItem = DirectCast(e.Node.Tag, TreeItem)

    ' If the selected item is an album...
    If ItemType.Album = item.Type Then

    ' Set the description
    picturebox.Image = Nothing
    ' Clear the image
    Return
    End If

    ' ...otherwise it is a photo
    ShowThumbnail(item)

    Catch ex As Exception
    MessageBox.Show(ex.Message)
    End Try
    End Sub
