Flip an image in Photoshop

Flip the entire project:

1. Click on “Image” and then “Image Rotation”
2. Here you can flip it horizontal or vertical

Flip single layers:

1. Select the layer you want to flip
2. Click on “Edit” and then “Transform”
3. From here you can flip just the selected objects

If you want to flip more than one layer inside a Photoshop file, than simply select all the layers by holding the Shift-key and select all of them.

Good luck!
