Only the people with subscriptions are able to do this.  But here is how to do it.

To add a pic to your player's profile you have to make sure it fits 96X96 pixels, (not inches but pixels) which you may size it in a photo editing type of program and be sure you save it as a .JPEG or .JPG which should be one of the "save as" options under where you give it the name as you save the picture.  So do your cropping, sizing and saving and then come to your Flyordie profile under the settings where you log in or log out.  You should be able to edit your profile there and upload the photo you just edited and also add a note about yourself.  :) Hope this helps!  Be sure the photo or graphics you upload falls under the guidelines of the rules okay?
