What is wrong in html
Your src of image is wrong and if you want that how to copy image links from Google see this question :- https://www.sololearn.com/discuss/2390690/?ref=app
I think the image url you are using is the location of the image on your device. You need to host the image online and then use the URL of that image.
but only online not from device add an image to html?
If you use the location of the image as url, you will be able to see the image in your local device. But if you want to host your website, the image needs to be hosted online and should have a url.
e_o you say that I need to host the image online and then use the URL of that image. But I don't know how to please explain
If the image is already hosted, you can copy it's url and try. To host the image yourself, you can use imgur, google drive, Dropbox etc. Just upload your image and use the shareable url.
