My comment was regarding an 8g image not fitting on an 8g card, not a shrunken image.? If you have an 8GB card and make an image file without pishrink, it will be an 8GB image file, even if I only 10k of that 8GB was used.? When you restore that file, if the card you used is spec'd by the manufacturer as 8G, but they use GiB for their "standard", then the image is 8192MB.? If the destination card you write the image to is also an 8G, but the manufacturer uses GB, it's free space is only 8000MB and the image will not fit.
GiB is the common standard, but disk drives, thumb drives etc depends on the manufacturer as to whether they use GB and GIB..
If the image was shrunk first, yes, only the used space of the original is all that it will be.? Unless it's a fresh image of Raspbian, it won't automatically expand the root filesystem to fit the card/drive it was installed on. You have to go into raspi-config, advanced options and expand filesystem then reboot.? Regardless of the size of the original image and card, that will only expand to the available unused size on the card

Sorry, but I don't agree with what you are saying. Here is an
example of why. I have a shrunk image that is 1.75 gigs in size. I
image that to an 8 gig card. So the completed card only has 1.75
gig of space used on it. Once it is moved over to the Pi, it still
only has 1.75 gig. The bit by bit copy is only of the 1.75 gig.
The copy process did not fill the rest of the card. Once the card
is in the Pi, the first time it boots, it boots up on the 1.75 gig
image and then immediately reboots to fill out the rest of the
space on the card. So in fact IT IS the OS that is doing it.
Nothing to do with the copying of the image to the card.

still makes a complete image of the card.?
