My friend: this is a great informative post. You cite the sources of the pictures, which is correct and it's great, the only thing you need to add, are the sources of the information.

That's how we make a good informative post. For the next time. I really liked it!

There are a lot of data that we know, but we also check in on the Internet. We need to share those sources. That's not plagiarism, that only means that you wrote your own post, but you've supported on written data.
