Why aren't my product images clickable on the 'Simple' theme?

[Kevin127]

I am having an issue where product images with transparent backgrounds are rendered atop when previewing:

Additionally, none of the other images are selectable.

The theme is ‘Simple’ and has had a modification for rendering a bulk count discount chart. However, this issue predates that particular modification (compared prior save).

An example URL: ushurling.com/products/tacoma-hounds-legs

There are very few apps configured:

…so before I start disabling/removing them, I was hoping for some additional guidance.

Found. It was some javascript imported by HulkApps into theme.liquid :

  {% include 'hulkcode_common' %}
  {% if template contains 'product' or template contains 'cart' %}
  	
  {% endif %}
