Made this guide for DeviantArt, but there is a section on How to Upload your images to NightCafe that is helpful, starting at Step 3. Free to use. Link to DA post included.
Thank you for sharing; it's the social aspect of NightCafe that sets this platform apart from other A.I. creation sites. Encouraging feedback, critiques, and interactions make NightCafe special. I'm guilty of spending waaaaaay too much time perusing galleries, but I truly am amazed by the creative ability of fellow artists and I have a strong desire to constantly improve; therefore, it's Artists, like you, sharing scroll-stopping creations, and taking your precious time to comment, that helps fuel my passion to create better and more beautiful art. Peace & Many Blessings To You...SMILE!!!
