Make JNG Files

JNG (short for JPEG Network Graphics) is a JPEG-based graphics format related to PNG. The JNG image format was originally created as a sub-format for the MNG files, but it can also be used as a standalone graphic format.

Although JNG images are created using JPEG lossy compression, they also contain an alpha channel that supports transparency.

When and if users want to create their own JNG files, they will have to select and use a specialized image converter with built-in support for this particular graphics format.
