Question:
FIWARE object storage GE: Different type of responses obtained when downloading an image object

Description:
I can effectively make use of all operations available for Object Storage on my FIWARE account.

Nonetheless I have identified a strange behaviour when downloading objects from a container.

Please find below the procedure to reproduce that strange behaviour:

I upload two objects ("gonzo.png" and "elmo.png") to the container "photos"
1.1. By means of cloud UI (https://cloud.lab.fiware.org/#objectstorage/containers/) I manually upload the object "gonzo.png"
1.2. By following the instructions from Object Storage GE programmer's guide I programmatically (or with the help of standalone Rest Client) upload the object "elmo.png"
I download the objects from the container "photos"
2.1 First, by following the instructions from Object Storage GE programmer's guide I successfully download object "gonzo.png". The webservice response body is the binary content of such object.
2.2. Later, by following same instructions as in step 2.1 I try to download the object "elmo.png". Now the webservice response body is a json with metadata and the binary content of the object.

What can I do receive a standard response body for both objects? Either binary or either json.
Why do I get a different response if the object is originally uploaded via Cloud UI or via external tool (program or rest client) ?
As in Download blob from fiware object-storage I have already tried to set the header response_type: text and the behaviour is the same.
