I am going to do a conference presentation on so-called Smart Cities
As you can imagine, the concept of a Smart City is best conveyed using pictures (it is worth a thousand words).
I found a picture which I think can capture this concept
There are others like it,
Since I didn't create them, therefore technically I think I should credit these images, but it is a lot of extraneously and unnecessary information for the audience.
I also see that many people do not credit images when they are presenting, and I would wager a guess that most of those images are not generated by themselves.
Should I attempt to credit or cite this image?
