Question again about favicon

Dear members, I have read all the threads about adding favicon, however I do not understand how it is done. I tried many times, however it is not working. How to add the favicon image to the pages and shoudl I export the site to the folder or I can see the effect right away? I did add the favicon line to head section in the property, with no luck

you have to manually put the favicon into your export folders, and then upload it to your hosting.
