显示图片问题'

图片框的页面代码是：
If Page.IsPostBack = False Then
lnkPic.Src = "showimg.aspx?id=1"

End If
showing.aspx代码是：
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim id As String
id = Request.QueryString("id")
Dim sqlcon As SqlConnection
Dim sqlcom As SqlCommand
Dim reader As SqlDataReader
sqlcon = New SqlConnection(ConfigurationSettings.AppSettings("Conn"))
Dim str As String
str = "select p01 from capimage where id=' & id & '"
sqlcom = New SqlCommand(str, sqlcon)
sqlcon.Open()
reader = sqlcom.ExecuteReader
While (reader.Read())
Response.ContentType = "image/*"
Response.BinaryWrite(reader(0))

End While
sqlcon.Close()
End Sub
现在的问题是：我lnkPic图片框是固定的，而且是要比图片大。当我运行时，则出现了，图片跟图片框一样的大，就是图片整个填充了图片框（图片变大了）。而我现在需要的是图片有多大就在图片框出现多大。请各位高手帮忙
