Thanks. I will try this too.

Now i'm using:

<dtml-with psychologie>
                <dtml-with mwfoto>
                <dtml-with "_[_.str(orggroup)]">
                <dtml-if "_.has_key(_.string.strip(mwid))">
                     <dtml-var "_[_.string.strip(mwid)].tag(align='right')">
                    <dtml-else>
                     <dtml-var "geenfoto.tag(align='right')">
                   </dtml-if>
                  </dtml-with>
                 </dtml-with>
                 </dtml-with>
                <dtml-var wie_is>

This works too. The stripping thingies are necesary because SQL server 7 or
the ODBC adapter fills out the field with blancs.
Setting border to "0":

<dtml-var "_[_.string.strip(mwid)].tag(border='0')">
