Step 1: Load a page on your website and view its source HTML.
Depending on your browser, you can access the source code by right-clicking on the page and selecting “View page source,” clicking “View the source of this page,” or by pressing Ctrl + U.
Step 2: Press Ctrl + F to search for a <script> element with src containing “lightboxcdn”. (Note: Don’t mistake DNS prefetch for an embed, it needs to be in a script element.)
Step 4: Click the Network tab, select type “JS”, add “lightboxcdn” as a filter, and reload the page. See the image below.
Step 5: Click the initiator for the first item loaded (lightbox.js).
Note the filename. In this case, it’s gtm.js, which is Google Tag Manager.
If you use another tag manager to deploy Digioh, you will see its associated file in this place. For instance, if you use Tealium, you will see Tealium’s Universal Tag (utag.js).
