To tell you the truth, I had a really hard time in parsing you message, since it seemed to be single sentence all lower-case, but it this what you were after

<xsl:template match="html:img">
  <img>
    <xsl:attribute name="src">
      <xsl:value-of select="$myfolder" />
      <xsl:call-template name="image">
        <xsl:with-param name="path" select="@src" />
      </xsl:call-template>
    </xsl:attribute>
  </img>
</xsl:template>

<xsl:template name="image">
  <xsl:param name="path" />

  <xsl:choose>
    <xsl:when test="contains($path, '/')">
      <xsl:call-template name="image">
        <xsl:with-param name="path" select="substring-after($path, '/')" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="concat(substring-before($path, '.'),'.wbmp')" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
