image ImageUrl

Dim Image1 As New Image
Image1.ID = "Image1"
Image1.ImageUrl = "~\phonelist\Photos\camera.gif"
Image1.Visible = True

<asp:Image ID="Image1" Visible="True" runat="server" />

I trying to do this in VB but the src keep coming up blank. I could do this on the front end but I need to make this dynamic for other reason. But why nothing appears in the src, that is a mystery to me.

<img id="ctl00_Attendance1_Repeater1_ctl00_Image1" src="" style="border-width:0px;" />

First of all if the image is already defined on your page (you already have: <asp:Image ID="Image1" Visible="True" runat="server" /> )
Why are you declaring a new image in the code behind? (Dim Image1 as new Image)

You could just do Me.Image1.ImageUrl = "~\phonelist\Photos\camera.gif"
Now it seem like your image control is in a repeater so you might wanna watch out for how you handle that...

Are you adding the control to the page
below code works good for me

Image img = new Image();
img.ImageUrl = "file.jpg";
Page.Controls.Add(img);

dim img as Image = Page.FindControl("image1") ' you may need to type cast the control to Image here
img.ImageUrl = "image.jpg";

Sorry nothing either if you create a repeater and test it you will see.
Dim img As Image = Page.FindControl("image1") ' you may need to type cast the control to Image here
img.ImageUrl = "~\phonelist\Photos\camera.gif"
