Pull up the History palette. You can do this by going to the Window --> History menu.

In Adobe Photoshop CS3, the History palette, as well as several other palettes, are docked in a bar on the right site of the screen. Click on the various icons to display the windows, or you can grab the windows and drag them to other parts of the screen.

The history palette will store every action you take in the program as a list. To undo, simply click on a previous item on the list and it will undo every action listed after it. If you complete another action, it will erase actions you've previously undone.

9. How do you rotate an image?
Go to the image menu and select Image Rotation.
