How to explicitly state the port number in an absolute URL?

Question

The question I'm working on:

mypage.html is stored in the folder Alice, in the folder Web Pages, in Root.
logo.jpg is stored in the folder IMG, in the folder Resources, in Web Pages, in Root.
Write the tag that will display the logo in mypage.html using an absolute url with scheme "http" and port "80".

Now, I (approximately) do most of this:

<img src="http:/webpages/resources/img/logo.jpg">

However I cannot find an example of how or where to specify the port number using a path like this.

Could anyone help point out to me where to include it? (And also if my progress above is actually correct?)

You don't need to explicitly state the port, 80 is the default for HTTP. — Quentin, Apr 18 '17 at 11:51

The port comes directly after the hostname, separated by :.

http://example.com:80/

http://example.com:80/path

That makes sense, however I'm a little unsure how to apply this to my specific example. Would it be http ://Root:80/webpages/... or http://:80/webpages/... or http ://webpages:80/... ? – Jonathan Apr 20 '17 at 09:16

@Jonathan: The hostname has to come first (and can’t be empty, like in your second example). A hostname is something like `example.com` or `www.example.org` or `localhost` etc. Can’t tell for sure what it should be in your case. But assuming that "webpages" is part of the URL path, it’s likely "root". – unor Apr 20 '17 at 14:43

http = Hypertext Transfer Protocol, use port 80 as default. You don't need to put :80 after the domain.

You need '/' after the http protocol:

<img src="http://webpages/resources/img/logo.jpg">

If the image is on the same server, you can use this:

<img src="resources/img/logo.jpg">

You're pointing to the resources folder, if your folder is on a lower folder level, you can use:

<img src="../resources/img/logo.jpg">

Thanks for your response. I understand that port 80 is the default for http but the question I'm answering seems to request that port 80 is explicitly stated rather than implicitly. – Jonathan Apr 20 '17 at 09:12
