Return a asp:image from codebehind

Hi!
I'm trying to return a image from a codebehind function, but the output is :System.Web.UI.WebControls.Image and not the image.
How to solve?
Code
Protected Function DisplayComment(ByVal serviceCoverageNotes As ServiceCoverageDAL.Intranet_ServiceCoveragesRow) As System.Web.UI.WebControls.Image Dim commentImage As New Image If Not serviceCoverageNotes.IsserviceCoveragesInfoNull Then commentImage.ImageUrl = "~/IntranetFiles/image/Icons_16/comment.png" commentImage.ToolTip = serviceCoverageNotes.serviceCoveragesInfo Return commentImage Else commentImage.ImageUrl = "~/IntranetFiles/image/Icons_16/comment_delete.png" commentImage.ToolTip = "Ingen information" Return commentImage End If End Function
