Hi, if I want to make a new website will it take the photography website I made away? Or is there a way to make another site on wordpress for free?
you can make it on a sub-domain as pictures.mywebsite.com or mywebsite.com is available for purchase - Sedo.com
thanks! will that cost?
Subdomains are free 
Some hosting companies/plans only allow 1 Wordpress installation.
Look through the ‘getting started with development’ recording - I clearly explain the steps of setting up a subdomain.
