dreamweaver how can i publish mysite freesite

You need a hosting platform. There are numerous hosting companies out there. If it will be a simple, relatively low traffic website then you're looking at about 2-5 dollars a month plus the yearly cost of your domain name.

Search for hosting companies, do some research, sign up with one, upload your html files and then your website will be live on the Internet.

PCMag has posted their list of the top hosting companies of 2017.

There are other options like running your own VPS but I don't know if that is what your looking for.

there are several ways you can do via the Remote Info setting in DW so that you can publish your site to online. have you exploring that before?

using filezilla i transfered my files to remote then how to continue next i am strugling

using a FTP client (like FileZilla) is just fine, it helps you transfer files over to remote server.

what you need to do is make sure:
1. you transfer the right files into the right folders
2. you can permission to transfer those files

ok, once the transferring is done, just try to access to that URL via your web browser. if everything's right then your web browser should reflect with correct web content.

sorry i can't get the way earlier explained 3 pages index.html contactus.html gallery.html  which url i don't hav webdomain address then hav to do as in free mode i got a order from my friend one website

free mode no paid

you would need a web server to host your web pages.

if you don't want to subscribe to a pay hosting service, you got to find the ones free for doing that.

Domain Names
If you have purchased domains registration/transfer or you have existing domains, please add them inside your Domain Manager section. Additionally, you should set the following name servers for all domains, except for the domains that have been registered with us.
Nameserver 1: ns1.your-hosting.net
Nameserver 2: ns2.your-hosting.net

Website Upload
Make sure you upload your files to the domain/subdomain directory on the server; otherwise, they will not be visible on the Internet. Also, please be sure that your homepage is saved as an "index" file e.g., index.php, index.html, index.htm, etc. We suggest you download some advanced FTP client to manage your files quickly or use the File Manager inside the Hosting Control Panel.

FTP Account Information
Your default FTP account information:
FTP Hostname: You should first add a domain/subdomain in your Hosting Control Panel.
FTP Username: 2453498
FTP Password: the one you have used upon registration
You can manage your FTP accounts from the FTP Manager section.

E-mail Account Information
To create an e-mail account go to the E-mail Manager section. E-mail account settings are:
POP3/IMAP server: mail.mydomain.com or subdomain.mydomain.com
SMTP server: mail.mydomain.com or subdomain.mydomain.com (check if you have this option enabled)
Username: the FULL e-mail address, e.g. something@yourdomain.com
Password: as specified upon creation

ok, so i believe you got a broken image:

just make sure it was uploaded to the correct path, else you may consider to change the image path in your HTML code.

To publish a site you need a hosting platform first so I first advice you to go through this list of best hosting providers.
