Oh yes ! Zoom is performed imediatly in memory without to allocate more memory space. \
Previous implementation recompute the whole image to scale it. This way is \
definitivly wrong !!!

Yes, a 100% button can be done, but for small image (with a size smaller than screen \
size), 100% zoom value will not work properlly in preview. Something is wrong in \
preview widget implementation (indeep)

Look screenshot from my computer...

Use Load and SaveAs button on the bottom of dialog...
