Hide element after it has been loaded onto the page

I have on my page the following google script: 

<body>
<!-- Google Tag Manager -->
<noscript>
  <iframe src="//www.googletagmanager.com/ns.html?id=GTM-abcdef"
          height="0" width="0" style="display:none;visibility:hidden">
  </iframe>
</noscript>
<script>
  (function(w,d,s,l,i){
    w[l]=w[l]||[];
    w[l].push({
      'gtm.start': new Date().getTime(),
      event:'gtm.js'
    });
    var f=d.getElementsByTagName(s)[0];
    var j=d.createElement(s);
    var dl=l!='dataLayer'?'&l='+l:'';
    j.async=true;
    j.src='//www.googletagmanager.com/gtm.js?id='+i+dl;
    f.parentNode.insertBefore(j,f);                    
  })(window,document,'script','dataLayer','GTM-abcdef');
</script>
...

When rendering the page, it inserts the following <img> tags at the end of my <body> 

  <img width="0" height="0" src="https://ib.adnxs.com/getuid?https://rxs.roixdelivery.com/delivery/counter?c=1255&amp;CHN=WEB&amp;apid=$UID&amp;rnd=939508138223"><imgsrc="//p.rfihub.com/cm?in=1&amp;pub=3657&amp;btag=2&amp;csurl=http%3A%2F%2Fs.thebrighttag.com%2Fcs%3Ftp%3Dqw8KooS" width="1" height="1" border="0">
</body>

These two images create a blank space at the bottom of my page, and I needed to insert display: none; into them to hide this space. However, I have some problems:

1 - Images are loaded dynamically by the script, so I have no control over them and I can not put any class to hide them.

2 - The selectors: $("body img:last").css("display","none"); e      $("body img:last").prev("img").css("display","none"); would work to capture them and apply the style, however they are loaded after the events $(document).ready() and $(window).load() and therefore the selectors do not work.

3 - I do not intend to use anything like setInterval, because if these images have not been uploaded yet after the period I specify, other images will be hidden in error. However, I'm sure these are the last images to load in <body>

How can I get around this?

I solved it!

I had not stopped to think that adding a css display: none with the selectors body > img:last-child and body > img:nth-last-child(2) would only make those images apply to the rule.

Thank you all for the help!
