How to specify Alt and Title in ASP.Net Image Control

hi

I used image control in page:

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

now I want use alt and title attribute for it like

<img src="services.gif" width="80" height="30" alt="services" title="services"> 

but there isn't any alt and title attribute for image control...

what should I put?
