But there is evidence presented. That means it is not any longer an argument from authority.
Argument from authority, as you have so duly quoted, and you also asserted that there was nothing more to it than what you quoted would be as such.
NASA says the earth is round
NASA is an expert
Therefore the earth is round
Now since there is evidence presented, we are no longer taking their authority at face value. We have evidence to discuss.
If you have an issue with the evidence, address that. Show us why it is wrong.
Otherwise we just have your authority on the subject to go by.
Also, you still have not shown us why all arguments from authority are logical fallacies when the page you yourself presented says that it is only a logical fallacy when misused.
I present you with this
An argument from authority (also appeal to authority, argumentum ad verecundiam[2] and argumentum ab auctoritate), when correctly applied, can be a valid and sometimes essential part of an argument that requests judgement or input from a qualified or expert source
and
The appeal to authority is based around the following syllogism:
Premise 1 - Experts on a subject are usually correct.
Premise 2 - Experts on the subject have a consensus that P is correct.
Conclusion - Therefore P is probably correct.
In its fallacious form, it could read:
Premise 1 - People with qualifications are usually correct.
Premise 2 - Those people say P is correct.
Conclusion - Therefore P is definitely correct.

is and authority on the subject, it is not fallacious at all to use their authority to form a valid argument.
Now if the argument was
NASA says trees need sunlight to survive
NASA is an expert
Therefore trees need sunlight to survive
Is fallacious reasoning, even though the conclusion is correct because NASA is not an expert in the area of arbology.
Also picked this one up to
Definition: Using an authority as evidence in your argument when the authority is not really an authority on the facts relevant to the argument. As the audience, allowing an irrelevant authority to add credibility to the claim being made.
http://www.logicallyfallacious.com/index.php/logical-fallacies/21-appeal-to-authorityBoth sites support my assertion that you are wrong in your assertion that all arguments from authority are fallacious.
So now that we have gotten past your attempt to do a bunch of hand waving so you can just ignore the evidence presented, why don't you just get on with telling me what you believe is wrong with the pictures presented.
