With imgur.com increasing limitations on anonymously-uploaded images, Later was in need of a new image hosting solution. Enter l4r.io, a purpose-built image hosting service for Later for Reddit.
How does it work! For you, it's simple – just select the "L4R" option when uploading an image, and you'll be using the new host. You can find full documentation here.
For now, this feature will only be available for paid users, but this may be expanded in the future. Keep an eye out!
