Restoring a resized image to its original size.

Is there a quick way to restore a resized image to its original size? I know I can double-click the image to bring up the scale sliders, but there is nothing obvious to indicate when the scaling is back to 100% — unless that is when the sliders are exactly in the middle, in which case maybe there could be a longer tick mark to indicate that, or even a “snap-to-100%” behavior. Or perhaps a button or a contextual menu item. Or a way to enter a percentage directly? Thanks.

I can’t think of a quick way, but you can right-click on the image and choose to save it out, then drag it back in—that will revert to 100% and would probably be the easiest. The other way would be to save it out, note down the pixel dimensions, and then set it accordingly in the project.
