Domain name selector

[kristo1980]

Hello,
I have a site in french and a site in English with two different domain names and two different backoffices, I want to add the possibility of switching from one site to another, I am not pro code but I think to add a Stuff like this in the header.tpl file of the two sites

The two shops are on prestashop 1.6

<p>Choose your language navigation</p>

<a href="https://www.site-francais/" ><img src="france.png" /></a></div>

<a href="https://www.site-anglais/" ><img src="anglais.png" /></a></div>

 

 

There is another way to do it can be cleaner and correct?
 
Thank you for your help
