Re: Organizing list of items in HTML table

Ooops, you need an additional test before filling the last row, in case the
number of columns divides the number of images evenly.  See correction
below.

*** Correction: above line should be:
          <xsl:if test="not(image[position() &gt;= $n + $numCols]) and
                            count(image) mod $numCols">
*** end of correction.
