Rotate a photo

Step 1 - Open the photo
Open the photo you want to rotate. If the image contains multiple layers, be aware that you can choose to rotate all layers or just the current layer.
Step 2 - Open the Rotate dialog
Choose Image > Rotate > Free Rotate, or press Ctrl + R. The Rotate dialog opens.
Perform this step for me.
Step 3 - Choose a direction
In the Direction section of the dialog, choose either Right or Left.
Step 4 - Set the degree
In the Degree section, choose one of the standard values (90, 180, or 270), or choose Free and then enter a value from .01 to 359.99 degrees.
Step 5 - Set layer rotation option
If you're rotating a single-layer image, you can ignore this step. But if you're rotating a multiple-layer image, mark the All Layers checkbox to rotate each layer. To rotate only the active layer, do not mark this checkbox.
Step 6 - Apply the rotation
Click OK to apply the rotation.
Notes and Tips:
If you only need to rotate an image 90 degrees, simply choose one of two commands: Image > Rotate > Rotate Clockwise 90, or Rotate Counter-clockwise 90.
If your image appears slightly crooked and this quick guide doesn't give you the desired results, try the Straighten a Crooked Photo quick guide linked below.
