Restore image ratio

[Afife]

Hello,

1/ What is the quickest way to restore an (embedded) image to its native aspect ratio ? (I don't have any external copy of this picture and after a lot of changes, I can't remember the original dimensions...).

2/ What is the quickest way to "extract" an image from my Publisher document to get it on the desktop ?

Merci !

I'd also like to know if it's possible to restore an image's ratio. I updated the source of a linked image and it updated in my picture frame at an incorrect ratio, even though the previous image was the correct ratio.
