AowVN an extension could probably implement such functionality, but that is out of our scope, as we are just a hosting provider and do not maintain Flarum core or it's extensions.
I understand that the speed at which forums are accessed is sometimes a problem in different regions across the globe. A pleasant solution might be to rent more servers. But servers cost money to rent (and FreeFlarum does not have any working or tested multiserver implementation yet, although I've drafted some in the upcoming rebase). I am not against multiserver architecture, but it would take time to get it working, and that would be a better solution - for now, you can prefix external image URLs in the posts at least, or hire/ask someone to create an extension with the desired functionality
