OK, here we are. Long live John Mitchell (and his blog posts...) 

     <asp:linkbutton id=cmdHelp tabindex="-1" runat="server" CausesValidation="False" enableviewstate="False"> 
<% If DotNetNuke.Security.PortalSecurity.IsInRoles("Administrator") Then%> 
           <asp:image id="imgHelp" tabindex="-1" runat="server" imageurl="~/images/help.gif" enableviewstate="False"></asp:image>
<%End If%>
    </asp:linkbutton>

He actually posted this to be used in skins for a permanent Admin Only displays. He also had "PortalSettings.AdministratorRoleName" in place of "Administrator"... It gave me some issues... so I just replaced it the way you see it here. Feel free to tell me what did I have to do to avoid hard coding  the role name.
