I need to change the widget from the previous threads

[almabetica]

I'm trying to change the widget "Recent Threads" so that instead of showing the avatar of the author, show the last user who has written on the subject. I think it's very simple, but I can not find the solution.

Here I leave the code:

PHP Code:

<div class="cms_widget">
    <div class="block">
        <div class="cms_widget_header">
            <h3><img alt="" src="{vb:stylevar imgdir_cms}/widget-forum.png" /> {vb:raw title}</h3>
        </div>
        <div class="cms_widget_content widget_content">
        <vb:each from="threads" key="threadid" value="thread">
            <div class="cms_widget_post_bit widget_post_bit">
                <div class="cms_widget_post_userinfo widget_post_userinfo">
                <vb:if condition="$thread['postusername']!='guestuser' AND $vboptions['avatarenabled']">
                    <div class="cms_widget_post_useravatar widget_post_useravatar">
                        <a class="comments_member_avatar_link" href="{vb:link member, {vb:raw thread}}">
                        <vb:if condition="$thread['avatarurl']" >
                            <img src="{vb:raw thread.avatarurl}" alt="{vb:raw thread.postusername}" />
                        <vb:else />
                            <img src="{vb:stylevar imgdir_misc}/unknown.gif" alt="{vb:raw thread.postusername}" />
                        </vb:if>
                        </a>
                    </div>
                </vb:if>
                </div>
                    <div class="cms_widget_post_comment<vb:if condition="!$vboptions['avatarenabled']">_noavatar</vb:if> widget_post_comment<vb:if condition="!$vboptions['avatarenabled']">_noavatar</vb:if>">
                        <h4 class="cms_widget_post_header widget_post_header">
                            <a href="{vb:link thread, {vb:raw thread}}">{vb:raw thread.title}</a>
                        </h4>
                        {vb:rawphrase thread_starter}:
                        <vb:if condition="thread.postusername == 'guestuser'">
                            {vb:raw thread.postusername}
                        <vb:else />
                            <a href="{vb:link member, {vb:raw thread}}">{vb:raw thread.postusername}</a>
                        </vb:if>
                        <p class="cms_widget_post_content widget_post_content">{vb:raw thread.previewtext}</p>
                        {vb:raw thread.lastpostdate}<vb:if condition="!$show['detailedtime']">, <span class="time">{vb:raw thread.lastposttime}</span></vb:if>


                        <vb:if condition="$thread['lastposterid']" >
                            {vb:rawphrase by_x, {vb:link member, {vb:raw thread}, null, 'lastposterid', 'lastposter'}, {vb:raw thread.lastposter}}
                        <vb:else />
                            {vb:rawphrase by_x_guest, {vb:raw thread.lastposter}}
                        </vb:if>
                        <a href="{vb:raw thread.lastposturl}"><img class="inlineimg" src="{vb:stylevar imgdir_button}/lastpost-{vb:stylevar right}.png" alt="{vb:rawphrase go_to_last_post}" border="0" /></a>
                        <vb:comment><br/>
                        {vb:rawphrase replies_x_views_y, {vb:raw thread.replycount}, {vb:raw thread.views}}</vb:comment>
                    </div>
            </div>
        </vb:each>
        </div>
    </div>
</div>
