Is that (with data taking the same number of bytes), or do you mean one could have something taking tags out of a source file, and storing them in a destination file, and changing the data for some of them along the way. (I don't know enough about the JPEG format to know if that description even makes sense - I just know that there's tags in them there jpeg files!) > Do you have any particular purpose in mind ?

Having a useful way to insert sensible meta data - which would typically be not about the image, so much as the subject of the image - could be really useful. It's something that in the past I've shied away from suggesting, for fear that I'd find myself committed to an unfunded research project to make it work! So I'd be very interested in this.
