Fundementally you need two loops.  an outer loop to select the first image
and every sixth image after that. And an inner loop to select that image and
the 5 following sibilings.

Hence:-

<xsl:for-each select="item[position() mod 6 = 1]">
    <xsl:for-each select=". | following-sibling::item[position() &lt; 6]">
      <img ...whatever />
    </xsl:for-each>
    <p ...throw page.. />
</xsl:for-each>
