So i'm configuring my custom core results web part for document search and I need to display bigger document icons, like ![](https://i.stack.imgur.com/qoqQz.png) instead of ![](https://i.stack.imgur.com/ouZUB.gif) for all document types. 

I found out that this part in xsl describes the icon: 

```
<div class="srch-Icon" id="{concat($currentId,'_Icon')}">                       
    <xsl:choose>
        <xsl:when test="isdocument='True'">
            <a>
                <xsl:attribute name="href">
                    <xsl:value-of select="concat('/_layouts/SPDocRedirect/SPItemRedirect.aspx?Type=filterid&amp;ItemId=',$listitemid,'&amp;Url=', url)"/>
                  </xsl:attribute>
                  <xsl:attribute name="title">
                    <xsl:value-of select="title"/>
                  </xsl:attribute>
                  <img align="absmiddle" src="{imageurl}" border="0" alt="{imageurl/@imageurldescription}" />   
            </a>
        </xsl:when>      
    </xsl:choose>           
    <xsl:choose>
        <xsl:when test="isdocument='False'">                
              <img align="absmiddle" src="{imageurl}" border="0" alt="{imageurl/@imageurldescription}" />   
        </xsl:when>      
    </xsl:choose>               

```

Can anyone suggest what should I edit in the above xsl? Thanks in advance
