Technical Requirements


Flash Player requirements:
You will need at least Flash player 9 to view the video material on this site and to be able to view the videos in full screen mode. If you do not have Flash 9 installed please download it from Adobe's website.

Browser support:
We do not support Internet Explorer 6. We took the descision early in the development of the new '' site to abandon support for IE 6, following the path set out by 'You Tube', 'Google' and many others. To support IE6, we would have had to spend considerably more time in development, producing a site which could be viewed in a old and buggy browser which was first released in 1991. We urge all our users to either upgrade, to use more modern browsers such as 'Firefox' or to lobby your organisation or educational establishment to abandon IE6 - if for no other reason, than that its security issues make it quite a liability.

Bandwidth requirements:
If you do not have broadband and are using a dial-up connection you will experience difficulty viewing our site. All our videos stream to your computer first before playing. If your bandwidth is insufficient to cope, the video will automatically stop until enough has been streamed ahead of the playhead. There are times however when increased usage may slow down our servers. These occasions, however rare, are unavoidable. Please try again after a period of time has elapsed and contact us, if you think there might be a technical problem with the site.

In order to use this site you must have Javascript enabled in your browser. Disabling Javascript will interfere with correct layout and organisation of the resources; in particular the 'accordian' arrangement of picture viewers, location information and so on. Please bear in mind that upgrading your browser or installing new security software or security patches may affect your JavaScript settings.
