I am actually trying to solve this problem as well. There has to be a way to config the build process for static sites that will be dropped into a normal web server. I am using gridsome on the frontend and only using strapi to do the hard work in dev mode. So all the images use this link on the web server
http://localhost:1337/uploads/Yht_F_Req_a77ce20079.jpg
All I want to be able to do is get rid of the localhost:1337 and maybe be able to state where the uploads folder is ex. /about/uploads/image.png
