+### getImages
+
+Fetches all images from within an element and puts them into an array
+
+Use `Element.prototype.getElementsByTagName()` to fetch all `<img>` elements inside the provided element, `Array.prototype.map()` to map every `src` attribute of their respective `<img>` element, then create a `Set` to eliminate duplicates and return the array.
+
+```js
+const getImages = (el, includeDuplicates = false) => {
+  const images = [...el.getElementsByTagName('img')].map(img => img.getAttribute('src'));
+  return includeDuplicates ? images : [...new Set(images)];
+};
