How to do it easier?

Question

MODX

Hello, how can I do better. there is a long block of very 40 pictures:

I need to show 6 pieces, others were hidden.
Conclusion:

[[!getPage?
         &element=`getResources`
         &parents=`17` 
         &tpl=`portfolioTpl` 
         &limit=`100`
         &sortby=`menuindex`
         &sortdir=`ASC`
         &includeTVs=`1`
]]

Where is portfolioTpl :

<div class="jackInTheBox gallery_product col-lg-4 col-md-4 col-sm-4 col-xs-6 filter [[+tv.material]]">
    <img src="[[pthumb? &input=`[[+tv.image]]` &options=`w=365&h=228&zc=C`]]" alt="" class="img-responsive" style="">
</div>

If I put 6 pieces, then it will not transfer products to other tabs, if everything is fully loaded, then the pictures are filtered. What's the best way to sneak?
