我可以从PictureBox图像添加Outlook附件吗?

我的VB.NET图片框中有一个图像。我想将其附加到通过Outlook发送的电子邮件中,而不必将其保存到驱动器的任何位置。有可能做这样的事吗?

这是我到目前为止所做的 here ):

Public Class email
    Dim app As Microsoft.Office.Interop.Outlook.Application
    Dim appNameSpace As Microsoft.Office.Interop.Outlook._NameSpace
    Dim memo As Microsoft.Office.Interop.Outlook.MailItem
    Dim outbox As Microsoft.Office.Interop.Outlook.MAPIFolder

    Public Sub New(ByVal attachment)
        Try
            app = New Microsoft.Office.Interop.Outlook.Application
            appNameSpace = app.GetNamespace("MAPI")
            appNameSpace.Logon(Nothing, Nothing, False, False)

            memo = app.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem)
            memo.To = "notmy@realemailaddress.com"
            memo.Subject = "Testing"
            memo.Body = "Hello there"
            memo.Attachments.Add(attachment, Microsoft.Office.Interop.Outlook.OlAttachmentType.olByValue)
            memo.Send()
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try

    End Sub


End Class
