How do you rotate image 90 degree?

Photoshop

To rotate an image 90 degrees, you can use image editing software like Photoshop or GIMP by selecting the image and choosing the rotate option from the menu (usually found under "Image" or "Edit"). In programming, libraries like PIL in Python allow you to use the rotate method to achieve this. For example, in PIL, you can apply image.rotate(90) to rotate the image clockwise by 90 degrees. Additionally, many operating systems allow direct rotation by right-clicking the image file and selecting the rotate option.
