First you need to get the reference for the photo that you will remove. You can use the url of the image or another method to access the reference of the image. The code below is directly from the Firebase Documentation.

StorageReference desertRef = mFirebaseStorage.getReferenceFromUrl(mImageUrl);

// Delete the file
desertRef.delete().addOnSuccessListener(new OnSuccessListener<Void>() {
    @Override
    public void onSuccess(Void aVoid) {
        // File deleted successfully
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // Uh-oh, an error occurred!
    }
});
