Model to train on large number of classes

So I am relative nooby in this:)
Just wanted to make an Image classifier to classify players from different teams. More than 200 players in total. Any specific approach I should use to take on such kind of problem?

What I mean is that what are the biggest differences between this and lets say Jeremy’s bear classifier?
How do I download the images? Individually and then put all of them into a folder? Or is there a another way?

PS: If anyone would like to work with me, its my pleasure:)
