view layout [
    img: image %yourimage.png
    button "rotate 90" [
        img/image: to-image layout [
            origin 0
            image img/image effect [rotate 90]
        ]
        show img
    ]
    button "save" [save/png %atestimage.png img/image]
]

so the modified image is saved back onto itself,
and pressing rotate several times continues to
rotate the image.

You will need recode it a bit for images where
width <> height, otherwise some info gets
chopped off.
