On Kunaki's FAQ page, it says you should upload your artwork as RGB 16-bit BMP or JPEG. However there apparently isn't a way to produce a 16-bit JPEG with Photoshop. It says in the FAQ that you can upload 8-bit images, but they "will not look very good."
Any graphics wizards out there who can advise me? Or anyone who has experience of using Kunaki and used their own artwork; what format / specs did you use and how did the finished product look?
Thanks in advance
