i mean to say is there any other EXIF tag which have offset and on that offset may be some data, just like image data.

http://www.awaresystems.be/imaging/tiff/tifftags/privateifd/exif.html This pages enumerates the EXIF tags

http://partners.adobe.com/public/developer/tiff/index.html This pages hold the spec

Private tags in general can't be allowed to have any major impact on the rendering process. That includes the EXIF tag. If not, the private tag scheme would harm interchange. You don't actually need to know any private tag in order to make sense of the image data.

Does that answer your question?
