You can bind the Visible property of your control to the expression and call DataBind() while the page is loading:

<asp:Image runat="server" id="image" Visible='<%#Eval("Image") != null %>' />

If you are not using server controls and want to show/hide simple markup, you can simply enclose it in an if statement:

<% if ( condition ) { %>
    <img src='<%= linkToImageSource %>' />
<% } %>
