I am not sure, if this is good task. There are articles that have images in some language Wikipedias but not in others. Typical example: article about some music album, newbie looks to en.wikipedia and "voila, there is cover image, lets add it to my wiki's article".
But this image is not on Commons. So part of newbies give it up. But second part will try to upload image to Commons or to home wiki, where will be problem because of en.wiki's fair use.
If there is item with commons category and this task will be active only for these articles, it's better, but also here are many categories without images (e.g. author with book scan in his category).
