Can I use file manager when store files on separate server?
I have two servers: website itself and the storage server where all my images are placed. It has domain prefix like
img.mydomain.com. How can I configure Flmngr file manager in this case?
There is no problem. You just need to mount you remote server directory with images into directory of Flmngr by NFS, Samba (Windows share) or using other way. That's all you need to upload images to remote server transparently.
If you want also insert images linked to separate domain, please also set
urlFiles in this way:
