Request: Can it be required to include your data source? Not a link to the data or anything (tho if that's available, awesome!) but just some general information in case anyone wants to share the image. For example, I teach and would love to include some of this info in my lectures, but I always try to cite where I got the info from. I can't do that if I don't know, so I can't use the info since I can't verify it's validity.
