Hmmm. Are you clicking on the little box just to the right of where it says Profile photo? If you are then all I can think is that your browser might be a bit old and you could do with upgrading to the latest version. Firefox is good.
OK. If you click on the settings link in the box in the top right hand corner of your screen, it should take you to a page that lets you edit your profile settings. Under your name is a little box labeled 'Profile Photo'. Click on that box and it will bring up an 'upload photo' box. Upload a photo from your computer and it should appear on your profile. Fingers crossed it should work. Good luck and let me know if it doesn't work.
Welcome to Ooooby Nickie. Nice photos. Have you had fun looking around the site? If you haven't had a look at the welcome page you can check it out here.
