It sometimes takes up to 24 hours for your Instagram account to show up in the Instagram API. To test this you can search for your username in the Instagram phone app. If you find your username, your photos should display in the app. If you do not find your username, check again in a few hours.
If after a few hours your username is still not visible, you should report the issue directly to Instagram here: http://help.instagram.com/customer/portal/articles/605537 and then report the bug here: http://bit.ly/reportanIGbug
