Thank you for your reply. If you try the second set of links (real bucket) you can see both images in any browser.
If you try to load them with a custom loader like bellow it works: <http://apache-flex-users.2333346.n4.nabble.com/file/t659/carbon_%283%29.png> Using firebaseImg.source=url; where firebaseImg is Image spark or BitmapImage, doesn't work. URL1 (works in all cases): https://firebasestorage.googleapis.com/v0/b/firebase-dogmate.appspot.com/o/ze.png?alt=media URL2 (works in browsers and loader but doesnt work for image.source=url) https://firebasestorage.googleapis.com/v0/b/firebase-dogmate.appspot.com/o/public_files%2Fze.png?alt=media Final step to solve this (after checking the BitmapImage.as code) was to submit a UrlRequest instead of string. firebaseImage.source = new UrlRequest(url); seem to work in all cases. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
