"src" in html context, means "source" and is an attribute of certains html elements, like <img> or <script> tags, for setting the address of a ressource:
<img src="url_to_img_file">
<script src="url_to_js_file"></script>

The src attribute instructs the browser where on the server it should look for the image thatās to be presented to the user. This may be an image in the same directory, an image somewhere else on the same server, or an image stored on another server.
The example refers to an image thatās located in the same directory as the web page thatās calling it, but if the image was stored in a directory that was one level higher than the referencing document, the syntax would be as follows:
<img src="../giant-prawn.jpg" alt="The Giant Prawn at Ballina"/>
Here, ../ equates to āmove up one directory in the hierarchy.ā
You can also reference an image relative to the web siteās root (that is, any file or folder after the domain name):
<img src="/giant-prawn.jpg" alt="The Giant Prawn at Ballina"/>
This basically means ādisplay the image giant-prawn.jpg that can be found in www.example.com/.ā This is a very handy way of referencing the file, as you could move the document that referenced the image to any location on the file system without breaking the link.
If youāre referencing an image thatās held on another server, youād express the src using a complete URI, as follows:
<img src="http://www.example.com/giant-prawn.jpg"
alt="The Giant Prawn at Ballina"/>
Example :
The src attribute for this image shows that the image is located in the same directory as the web page:
<img src="giant-prawn.jpg" alt="The Giant Prawn at Ballina"/>
