Atanda Waheed Olaide ,
that's not valid image URL.
It's pointing to webpage not the image.
Use this url instead:
https://i.postimg.cc/fb8vTdZP/Oba-Sijuade1.jpg (This is from webpage that you have linked in code)
When you visit a page long press on image and choose option "Open image in new tab". In new tab copy url from searchbar.
