Use a bit(Boolean) in a DataList

[Metalzed]

Hi i have a table with my message. With a query i get the values Namn(varchar(50) , Message(Text) , Sent(datetime) , Seen(bit)

The Namn , Message and sent i just want to write out and it works.
But with the seen i dont want to write true or false or 1 and 0. I want to change a image..

How does it work? I dont have a clue to where to begin.

Here is my code that works today.

 
 
<asp:SqlDataSource ID="SQL_LAS_MESS" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
        SelectCommand="SELECT TB_MESSAGE.MESSAGE, TB_MESSAGE.SENT, TB_USER.NAMN, TB_MESSAGE.SEEN,
TB_MESSAGE.FROM_ID FROM TB_MESSAGE INNER JOIN TB_USER ON TB_MESSAGE.FROM_ID = TB_USER.USER_ID WHERE (TB_MESSAGE.TO_ID = @TO_ID) ORDER BY TB_MESSAGE.SENT DESC">
        <SelectParameters>
            <asp:QueryStringParameter Name="TO_ID" QueryStringField="USERID" />
        </SelectParameters>
    </asp:SqlDataSource>
 
 
    <asp:DataList ID="Guestbook_List" runat="server" DataSourceID="SQL_LAS_MESS">
 
        <ItemTemplate>
            <table border="1">
                <tr>
 
                    <td>
                        Från :
                        <a href="USERPAGE.aspx?USERID=<%# Eval("FROM_ID") %>">
<asp:Label ID="NAMNLabel" runat="server" Text='<%# Eval("NAMN") %>'></asp:Label></a>
                    </td>
 
                    <td>
                        <asp:Label ID="SENTLabel" runat="server" Text='<%# Eval("SENT") %>'></asp:Label>
                    </td>
                </tr>
 
                <tr>
                    <td colspan="2">
                        <asp:Label ID="MESSAGELabel" runat="server" Text='<%# Eval("MESSAGE") %>'></asp:Label>
                    </td>                    
                </tr>
            </table>           
        </ItemTemplate>
 
        <HeaderTemplate>
            Gästbok
        </HeaderTemplate>
    </asp:DataList>
