Basically ive found the best (and easiest) solution seems to be to create a discord server and upload my sneak peeks to a private chat.
So thats what ive done :)
Ive amended all of my pledge tiers now to include access to a private discord server so you can view my Sneak Peeks. (Im assumin that if youre already pledging itll grant you access but if not then just message me and ill send you an invite link).
When you join the server youll be put into an "unverified role" and you wont be able to view the private chats until i manually change your role to verified.
