Rotate and Invert an image

Yes. From memory Image > Rotate

Indeed, I believe we used to have an item there that allowed "flipping" an image horizontally or vertically. That seems to have gone missing. I was looking for it just a few days back.

What I ended up doing was grabbing a side sizing handle and dragging it so it "squished" the image to nearly nothing but then going beyond the opposite sizing handle. Once it goes beyond the other sizing handle, it's  then been effectively "flipped".

Note that you may need to expand the canvas before this process as well as selecting the entire image and choosing to copy it first. Then paste it back in so it becomes a layer that can be manipulated.

Cheers... Rick :)

Flip Horizontal and Vertical can be found under the "Arrange Tab" under the "Image" tab.
