Also, people will focus more on the aesthetics of the food, how the food looks, than the taste, and since there will be no way to taste everyone's meal, winning will be based on aesthetics and presentation.

We can't guard against it; it's better to be helped than to steal images from the internet; presenting the method of preparation is what counts most. Similar to the pizza contest, what you do behind the scenes is nobody's business; just show the preparation procedure.
Yes, food aesthetics will be a big factor it an online contest.
