Q:

Img Src tag in Html not Working regardless any reference link type

I was editing an HTML page and had some issue in replacing image. It didn't displayed anything.
Then I tried making a simple HTML program just to test
<html>
<head>
<title>
</title>
</head>
<body>

<img src="/images/Kanhaji.jpg" alt="HTML5 Icon" width="128" height="128" />

</body>
</html>

but it still doesnot work.
I tried Everything Including but not limited to 
1. Giving local links in same directory in which my page is.
2. Creating a subDirectory and giving its link.(as shown above)
3. Giving full path
4. using <image src="./Kanhaji.jpeg" /> (proper reference methods ./ ../ etc)
5. Using an Online Link <image src="https://I_cannot_remember_the_url_exactly /> 
6. Hard Refreshing page ctrl + f5 in case if browser is using cached contents somehow. But nothing seems to work
only a box,where image is supposed to appears, with a broken image icon appears.

<img class="rounded-circle img-fluid d-block mx-auto" src="http://placehold.it/200x200" alt=""> 
 the above code is working fine
after watching it working , i tried to 
7.remove extension of file if it is effecting somehow but that also didn't helped
Can anyone help me with this problem.
