With a small image (credits on the image) plucked from the internet flipping an
image is straightforward

see: http://i.imgur.com/q1NHxFx.jpg

1. Use the flip tool

2. Make sure you are on the active layer with **No** active selection.

3. Need to be on the layer mode and select either Horizontal or vertical

4. Probably the bit you are missing, click on the canvas to implement.

Just a caveat, I use linux so I cannot demo anything 'Mac' However I can do a
little research and the McGimp 2.8.14 from www.partha.com does include many
extras including the liquid-rescale plugin. Worth trying because it also
includes other scripts and plugins such as heal-selection.

In my linux Gimp using liquid rescale might go something like this

It all depends on the image and the amount of re-sizing. For small-ish amounts,
sometimes possible to re-size the canvas, copy and paste a strip back in and a
bit touching up.

depends on the image/requirements.
