How to flip an image in Sparkle software

Hi I’m trying to Flip an image .jpeg, format, I’ve copied it ok, but I want to flip it from left to right to right to left to the pair of the same image can sit side by side…
Could anyone help
Many Thanks
Regards Fil

The easiest way is to duplicate the image then grab one of the left or right resize handles and drag it over to the opposite direction. This will flip the image.
