I used to use jpg2000 to work with aero-photos in AutoCAD.
IIRC Jpeg2000 has support for world coordinates and a kind of embed
multimap (I forgot the right name, maybe multisampling).

Are you planning to support this as well? (maybe some interface to
assign a relation between Blender coordinates and the photo
