To better understand the problem i would like to see the img tag and how you are calling showanswer.

when a control has runat="server" the client id is composed with all the container controls that he has.

example
my id "linkSelection" becomes "ctl00_ctl00_MasterContainer_menu_linkSelection"

you can match the final part of the id

JavaScript

<script type="text/javascript">
        function showanswer(sender, divid) { $("[id$='"+ divid +"']").slideDown(400); }
        function hideanswer(divid) {$("[id$='"+ divid +"']").slideUp(300);}
    </script></script>

or you can use

XML

<asp:TextBox ID="txt_answer" runat="server" Height="74px" TextMode="MultiLine"
            Width="296px"></asp:TextBox>
        <br />
        <input id="Button1" type="button" value="Submit" onclick="PostAnswer('<%= div_answer.ClientID %>')" />
        <input id="Button2" type="button" value="Cancel" onclick="hideanswer('<%= div_answer.ClientID %>')" />
