In case あなた don't know how to, go to your プロフィール page. 次 to your personal info (in case you've added that already) there should be a link saying 'view もっと見る photos'. Click on it. Find the link saying 'upload new photo' in the dark blue colored beam. It has a plus 次 to it. From there, あなた should be able to アップロード images.
I can アップロード them without any problems, so あなた should to. If not, the problem might be in your PC. Anyway, good luck!
