A good question SG.
Click on the avatar photo on the left. Then you will see 'Crystal Points' and a number next to that. Click on that number.
When you are viewing your own profile ('Your Profile Page' link under your name top right) you will also see the crystal points and you can click on that as well. It will bring up the same screen.
To make this even easier, I just edited the templates for both styles and added this link which can be found when viewing your profile details (not profile page, but the other links relating directly to your profile)
This system doesn't allow images/icons. There are add-ons that implement such a thing.
