You have just used another logical fallacy.
Having some degree or credentials in some subject or field doesn't make you automatically an expert in other fields. Despite that having getting a degree in some faculty doesn't necessary mean that someone is an expert neither. To be an expert in the field with good credentials, it takes years of producing legitimate research and establishing position in the filed.

Just the fact that you have used that ignorant and generic response "I didn't get my academic degree and credentials out of a cereal box.", says something about your ability to for logical discourse.

This logical fallacy is called "Appeal to Accomplishment".
It can be also "Appeal to Authority" where you claim yourself to be authority in the subject of copyright (because you have expertise/educational degree in something other subject).
Although you have no expertise in this subject, so appealing yo yourself as authority in the subject of authority would then be "Appeal to non-authority).

But knowing about that might be too steep of a learning curve for your protegee

Another "ad hominem".

You may have got some degree in something but you seem to fail to be educated about the basics of logical discourse, as you have proven over and over again. And this could be have been ad hominem directed at you, if you had not proven otherwise.

The information in "vagallery" link that you have provided only supports the idea of proper sourcing and giving credentials to the author, which was given by jaguar.force, as he gave the source and showed credentials of the artist.
