    {{for xxx in records:}}
    <tr>    
        <td>
            <img width="150" src="{{=URL(a='Assignment', c='default', 
r=request, f='download', args=xxx.Picture)}}" alt="no picture provided" />
            <!--This line above is exactly what i copied from the slides -->
        </td>
    {{pass}}
      </tr>
