I would like to tag a "Button" that makes each image in the gallery visible to me. Each image will have a different tag which will then be displayed in analytic events. I think this is the only way to be able to analyze gallery visits without a url.

<a onclick="document.getElementById('id001').style.display='block'" class="item-link">
          <img class="miniatur" src="img001"/></a>

The tag I believe is of type:

?utm_source=facebook&utm_medium=cpc&utm_campaign=campaignname&utm_content=adsetname--adname

But where do I write it?
