Photos not showing, previously worked

Hello, Photos are not pulling through for two iFrames that were formerly working. Could you please fix this, or advise me on how to fix on my end? iFrame URLs: http://snapwidget.com/p/widget/?id=6Uy9uC7b3p&t=247 and http://snapwidget.com/p/widget/?id=iewt6Jkf9v&t=372 Thank you, Mike
