Issues with media posted on Timemapper


I am having some issues with photos (hosted on Flickr) appearing on my Timemapper creation.
Is there any particular reason why they sometimes appear, and other times, do not? It does not appear to be a browser or connection issue. My Timemapper is on my Omeka site.
I also am having problems getting any youtube or vimeo videos to embed and play.
I am concerned as the site and contents are an artefact prototype accompanying my Masters dissertation at the end of August.
Any help is very appreciated!
