If you want to create a website using Pics.io, usually you want it to be available at an address like john.org.ua, not something like show.pics.io/hkh3ueh3282938383 that goes by default.
Well, that’s easily achievable:
1. Go to the website where you’ve registered your domain name (GoDaddy, IwantMyName, etc.)
2. Find DNS preferences of the domain name you want to connect to Pics.io
3. You need to change A-records of your domain:
*.yourdomain.com should be associated with 220.127.116.11 ip address
@.yourdomain.com should be also associated with 18.104.22.168 ip address
You can leave MX records untouched. Once you finish setting up the right A-records, save them and wait one day for them to apply.
After that you’ll be able to enter your domain into the link field in Pics.io.
If you want to create a dedicated gallery, just add a word after the last slash (i.e. http://kshtondenko.com/gallery) and click Create website.
