One of the features of the #Reasonator is that it will indicate when pictures are available in #Wikipedia articles. It takes several steps to add a picture and, many pictures have been added in this way.
With the latest iteration of FIST, the Free Image Search Tool, Magnus has revamped an existing tool and gave it a new lease of life as a tool for Wikidata.

As a tool for Wikidata FIST is still raw around its edges, it may time out its session for instance. However, it is such a nice tool; it deserves to be used.
