hi, is there any way to make it so people can download skins in local host dedicated server? like possible to upload it into the server directory and then people can download it? ty

No that is not possible. Only way to share skins automatically via LFS is through LFS world. If you want this type of thing you will have to upload them yourself somewhere, and then provide people with the link, maybe a password protected FTP location or something. Or photobucket account with password access. =)
