 If you're seeing broken image links or missing photos after following these steps, you may need to open your browser's
 dev tools and clear both [localStorage](https://developer.chrome.com/docs/devtools/storage/localstorage) and [IndexedDB](https://developer.chrome.com/docs/devtools/storage/indexeddb).
+
+In localStorage, look for domain `http://localhost:8100` and key `CapacitorStorage.photos`. 
+In IndexedDB, find a store called "FileStorage". Your photos will have a key like `/DATA/123456789012.jpeg`.

 That’s it! We’ve built a complete Photo Gallery feature in our Ionic app that works on the web. Next up, we’ll transform it into a mobile app for iOS and Android!
