I want to redirect list view form images to detail view form for clicking of images but it’s not work even I use different combination in <a> tag

1-<xmod:field name="Thumbnail"  usevalue="true"/>   

2-<xmod:field name="Thumbnail"  usevalue="true" detaillink="true"/>   

3-<xmod:field name="Thumbnail" />

4- Remove <a> then no result find.

<xmod:listviewstyle repeatdirection="horizontal" repeatcolumns="3" borderwidth="0" cellpadding="0" cellspacing="13"  bordercolor="#123456" prevtext

="Prev" nexttext

="Next" showheader="true" showpager="true" forecolor="black" class="NormalBold" align="center" />

<table border="0px" width="146">

    <td align="center"><a href="<xmod:field name="Thumbnail"  usevalue="true"/>"><img border=0 src="<xmod:field name="Thumbnail" usevalue="true"/>" alt="<xmod:field name="Caption"/>" /></a></td>

  </tr>
