Thank you for your response, please note this carefully!

In steemit you can only use external images if they are images that you take from web copyright-free image providers or images licensed by creative commons.

You may not use images carelessly even if you enter a source, if the image you use is identified as copyrighted.

Please go to pixabay, unsplash, pixel, wikimedia or freepick, you will find lots of free images there which you can use for free with the terms of their license,

I hope you understand.
