    I’m using the Firebase plugin along with nativeUtils.displayImagePicker and nativeUtils.displayCameraPicker to upload images to the Firebase Storage via uploadFile. However, when I do this, Google doesn’t see the image as an image file but shows it as Type: “application/octet-stream”, whereas if I upload an image directly through the Firebase Console is sees it as Type: “image/jpeg”. I wouldn’t normally mind but I added the “Resize Images” extension to the console and it doesn’t see the images uploaded through Felgo as images and therefore doesn’t resize them (images I manually upload through the console are resized as expected).

    So, if there is a way to automatically resize images before uploading them, that would work well, otherwise, is there a way to get Google Firebase to recognize images as actual images? I’m using the code provided on this website.

        AppButton {
            text: "Add Photo from Gallery"
            flat: false
            onClicked: {
                nativeUtils.displayImagePicker("Pick Image")
        Connections {
            target: nativeUtils
            onCameraPickerFinished: {
                if(accepted) {
            onImagePickerFinished: {
                if (accepted) {
            function uploadImage(path) {
                var remote_path = "users/" + dataModel.user_id + "/test-image" + + ".jpg"
                fbStorage.uploadFile(path, remote_path,
                                     function (progress, finished, success, downloadUrl) {
                                         if (!finished) {
                                             status.text = "Uploading... " + progress.toFixed(2) + "%"
                                         } else if (success) {
                                             console.debug("downloadUrl: ", downloadUrl)
                                             status.text = "Upload complete"
                                             photoModel.append({p: path})
                                         } else {
                                             status.text = "Upload failed"

    Thank you,

    Hi Eric,

    thanks for this report. I’ll have to forward this to the plugin development team and hope to get an aswer for you shortly.
