Rest classify doesn't return images

[alemela]

Probably after the new getImage implementation the rest API classify broke. Images are always "".

Tried with some examples including the suggested one:
curl -F text="The final work of legendary director Stanley Kubrick, who died within a week of completing the edit, is based upon a novel by Arthur Schnitzler." -F numTopics=7 -F lang=english -F key="" http://tellmefirst.polito.it:2222/rest/classify
