When changing any data of a Contact that happens to already have
a "large" image assigned, the Image Resizing Dialog is intrusive
and always asks the user again.


Steps to reproduce:
* Add an image to Contact, that is assumed tobe "large".
  108x108 Pixels is sufficient, 96 is the threshold AFAIK.
* Save the Contact and choose "No" to save the image as is without resizing.
* Edit that Contact again. Change any value, not related to the image,
  for example adding a Note. ave it.

The Image Resizing Dialog pops up yet again. Despit the fact the image was added previously and I did *not* change the image in any way.


The Image Resizing Dialog should be triggered *only*, if
a) an image was added or changed, and
b) the new image happens to be "large".
