My experience teaching university students has led me to believe that they don’t know enough about how to attribute images that they haven’t created themselves. From my own experience as both a student and a teacher, I am familiar with applications that make creative bibliographies much easier (BibMe, EasyBib, etc.). I am also familiar with what happens when it’s easy to correctly create bibliographies and citations; I (and others) are much more likely to make sure we’ve give credit where credit is due.
