I have a multisite WordPress install with a large uploads folder. I want to setup multiple staging areas both on the local and remote server. But this way, it will take quite a lot of disk space. So I wonder if I can use the uploads folder from the live site for all these staging areas, e.g., load all images from mysite.com on mysite.dev and test.mysite.com and load images from the corresponding network site for other network sites.
I found a plugin called Uploads by Proxy but it does not work with multisite installs. Is there any plugin solution to achieve this? I thought also of replacing image URLs in the database but this is going to be a regex replacement and this is going to take too long each time I update the database.
