let's say you have some projects as subresources in your portfolio-page
each project-resource has some MIGX-images.
Then you would put getResources to your portfolio-page to get the projects:
<ul>[[getResources? &tpl=`yourProjectTpl` &parents=`[[*id]]` &includeTVs=`1` &includeContent=`1`]]</ul>
yourProjectTpl is a chunk with name 'yourProjectTpl' , you can name it as you like.
content of yourProjectTpl something like that:
<li class="project">
<h2><a id="[[+pagetitle]]" name="[[+pagetitle]]"></a>[[+pagetitle]]</h2>
<div class="proj-content">
<div class="url"><a href="http://[[+project_url]]">[[+project_url]]</a></div><!--end url-->
<p>[[+content]]</p>
<div class="proj-box">
<div class="slides">
<div class="slide-nrs">1 of 1</div>
[[getImageList?
&docid=`[[+id]]`
&tvname=`project_item`
&tpl=`yourProjectImageTpl`
&pagetitle=`[[+pagetitle]]`
]]
<ul>
<li>Design</li>
<li>CSS/(X)HTML</li>
<li>Programozás</li>
</ul>
</div><!--end slides!-->
</div><!--end proj-box-->
</div><!--end project content-->
</li>
the chunk 'yourProjectImageTpl'
[[+idx:is=`1`:then=`
<a rel="shadowbox[[[+property.pagetitle]]]" title="[[+property.pagetitle]]" href="[[+image]]">
<img width="589" height="400" alt="[[+property.pagetitle]]" src="[[+image]]"></a>
`:else=`
<a href="[[+image]]" class="structural" title="[[+property.pagetitle]]" rel="shadowbox[[[+property.pagetitle]]]">[[+property.pagetitle]]</a
