When i upload images to Nuxeo, there is no preview and the file is renamed as "empty_picture.png"

Why when i upload png and jpg images to Nuxeo 6, the preview is not generated, and the file associated to the picture is renamed as "empty_picture.png". Why?

I think this problem is because of the absence of nuxeo-dam addon. Many features of nuxeo such as preview, annotations etc., are dependent on this add-on. Download this add-on from nuxeo marketplace and install it (Refer the attached image). Don't forget to restart the server. Please let me know this solution works for you.
