If document.querySelector fails to find the elements, gallery or largeImg will be null which will cause runtime errors when adding the event listener or setting .src. Consider guarding against missing elements or ensuring the DOM elements exist before running this script (e.g., run after DOMContentLoaded or check for null).

Good: you wrapped initialization in DOMContentLoaded and use event delegation. However, there's one remaining risk: if the querySelector calls fail (elements missing), gallery or largeImg could be null and calling gallery.addEventListener or assigning largeImg.src would throw. Add null checks after selecting them and exit early (or guard uses). This ensures robustness if elements are absent.

When comparing tag names, event.target.tagName returns an uppercase string in all browsers; your code compares to lowercase 'img' and 'a'. This will make the conditions never true. Use uppercase checks ('IMG', 'A') or normalize with .toLowerCase() on tagName.
