Most of the people will tend to use a unique display picture as their icon online. For example, you might use a special image or your own picture to specially label yourself to be found more easily. A lot of the instant messaging software like MSN, iChat, Skype or your display picture on your own system. Usually if you want to rotate your picture at a certain angle, you will use some other third party software to do that and then crop out the part you need for use as display picture.
The fact is that, Mac OS can make it easier.
When you have a display picture select windows or preview windows in the software, you can just hold the “Option” key, while place your mouse cursor on top of your display picture, you will see a clock-like protractor on top of your original picture. Now you can just hold the left button of your mouse and rotate the picture at any angles you want.
