remove link in summary view

[robertprynkiewicz]

I would like to remove the link in the image that goes to the detail view of an item in the directory. I am looking at the php file sub_listingSummary.tpl.php and do not know where to edit the file in order to basically make the thumbnail image static and not a link.

this is the summary page:

https://smithlib.org/resources/databases.html

Again, I want to remove the link in the image.

Thank You
Bob
