1) wat, you have 2 <img> tags there 2) the second img tag has an <img> in its src attribute 3) file:///C:/Users/nec/Desktop/Don't%20delete/screenshot_000003.png is a file on your computer, no one else on the internet could have viewed it unless they have the same file at the same precise location
You can't sadly just host images from your own computer without uploading them to an intermediate provider such as imgur. Upload your image there and copy the direct link into the src attribute of your tag.
<img src="file:///C:/Users/nec/Desktop/Don't%20delete/screenshot_000003.png" alt=""> It's a file on your computer all right. You need a URL for your pic for this to be seen by others.
