their names.here is my code

<li class="bitem">
<xsl:variable name="brandLogo">

</xsl:variable>
<xsl:choose>
<xsl:when test="XSLTHelper:FileExists($brandLogo) = 'true'">
<a href="/search?query={@name}&amp;searchField=Brand">
<img
src="/images/imagehandler.ashx?path=/images/logo-images/{@name}_logo.jpg&amp;width=100&amp;height=60&amp;constrain=true&amp;pad=false"
