There's no "Rotate Snap Image" function

[Fonte Boa]

Really "Rotate Snap Image" would be welcomed to complete Snap Image tools.

It would involve memorizing how much I rotated it in order to snap the image, and then rotate it back that amount.

Probably you already know, but, during rotate operation (and all the other ones), when you reach the desired amount, before Left click to execute, you can hit TAB key: this will open the Numeric Input window and you can verify there the exact rotation angle (unfortunatelly you will have to note that in a paper, because it isnt possible to copy it to paste after...).
