[Insight-users] How to set sizes of images

[Hila Hiler]

Thank you Dzenan,

actually, I looked again at the image's details. It seems that the
alignment process might be more complex than I thought because not just the
dimension are different but also the spacing, origin etc.


The details are attached.
please help to figure this up ...
