How can I 3D-rotate an image around the y-axis in Photoshop?
Solution 1:
You should be able to simulate the effect by applying a perspective transformation.
The option is Edit > Transform > Perspective or you can grab a corner with Ctrl + Alt and then hold shift down while dragging

Solution 2:
If you do actually want to rotate the z axis to create a 3D effect you must have Photoshop CS4 Extended or higher to do this:
- Select your layer, then the 3D menu (inbetween Analysis and View), and New 3D Postcard from Layer
- Toggle the 3D rotation tool, which is 4th from the bottom or press K for its shortcut key
- Rotate away
