Rotating an image from the thumbnail panel

To rotate an image,

1. Click the thumbnail representing the image file you are going to rotate.
2. Click the Rotate button.
3. Select the degree with which you are going to rotate the image clockwise from the menu that has just popped up.

tkDerm permits only the user who logged in as the tkDerm superuser to do this action because it will result in a change of the image file. When you log in as a user other than the tkDerm superuser, the Rotate button will remain disabled even if you select a thumbnail. tkDerm superuser means the user who initialized tkDerm. See Section 1.7 ( page).
