And therein lies the paranoid tin-hat tosh.
New Image Format will need a new Image Editor
No one, and I really do mean no one, is going to start using an entirely new image editor just to support a new format. As for embedded data, any image format that supports meta data will suffice for that (e.g. dare I say it, JPG - yikes).
Also, it is more or less meaningless to scan images for viruses unless or until a fault is found in the image rendering software thus making an exploit possible.
