Very nice article. There are also many other free websites apart from the ones mentioned in Step One. We can use it from those websites as well. There are also few very good photographers available in Instagram, they give their photos under CC0 licence. We can also use them. The below post was from @steemstem community. It also has some valuable information. Just an addition to this wonderful article.

And thank you very much for reinforcing the need of sourcing things correctly!Hi @bala41288, the websites mentioned on step one are mere examples and perhaps the most well known ones. Obviously, if someone is truly interested in doing things right will not have any issues finding others.
