Allowing rotation of images

Sometimes images are necessary to implement an alternative symbol in a certain way under certain circumstances. It would be a +1 to this approach if, like "Allow Diagonal" with crescendo or lines, an "Allow Rotation" checkbox were implemented to "spin" an image into a certain angle. This might sound superfluous, but it could help the alignment process for certain situations without having to alter the image further in another program. Just something to think about.
